“GTP” Glycol feed packages are a turn key system designed to feed glycol in the event of system pressure drop. The glycol feed package then pumps glycol until system pressure is restored. This will sure that the make up to the system is being maintained with glycol. An efficiently fill maintained system can save the client on their energy bills.
Historical aspects and natural occurrence
Ethylene glycol was first prepared in 1859 by the French chemist Charles-Adolphe Wurtz from ethylene glycol diacetate via saponification with potassium hydroxide and, in 1860, from the hydration of ethylene oxide. There appears to have been no commercial manufacture or application of ethylene glycol prior to World War I, when it was synthesized from ethylene dichloride in Germany and used as a substitute for glycerol in the explosives industry.
In the United States, semi-commercial production of ethylene glycol via ethylene chlorohydrin started in The first large-scale commercial glycol plant was erected in 1925 at South Charleston, West Virginia, by Carbide and Carbon Chemicals Co. (now Union Carbide Corp.). By 1929, ethylene glycol was being used by almost all dynamite manufacturers.
In 1937, Carbide started up the first plant based on Lefort's process for vapor-phase oxidation of ethylene to ethylene oxide. Carbide maintained a monopoly on the direct oxidation process until 1953, when the Scientific Design process was commercialized and offered for licenses.
This molecule has been observed in outer space.

5. Sales Training
The major end uses of ethylene glycol are as an antifreeze, which accounts for over 50% of ethylene glycol's commercial uses, and as raw material in the production of polyester fibers, mainly PET, which accounts for 40% of total ethylene glycol consumption. Because this material is cheaply available, it finds many niche applications.
Coolant and heat transfer agent
The major use of ethylene glycol is as a medium for convective heat transfer in, for example, automobiles and liquid cooled computers. Ethylene glycol is also commonly used in chilled water air conditioning systems that place either the chiller or air handlers outside, or systems that must cool below the freezing temperature of water.
Pure ethylene glycol has a specific heat capacity about one half that of water. So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water. A 50/50 mix by mass has a specific heat capacity of about 0.75 BTU/lb F, thus requiring increased flow rates in same system comparisons with water. Additionally, the increase in boiling point over pure water inhibits nucleate boiling on heat transfer surfaces thus reducing heat transfer efficiency in some cases, such as gasoline engine cylinder walls. Therefore, pure ethylene glycol should not be used as an engine coolant in most cases.

11. Receiving & Inspection
Upon receipt of order, inspect package thoroughly.
In the event there was damage incurred in transit you must notify the freight company within 3-5 days of receipt of order. Once system is inspected for damage and received in good condition, and store indoors in safe place until installing. Damaged incurred before installation is not covered under warranty.

12. Installation & Operation
Before you get started…
All fasteners and fitting should be properly inspected and secured before operation as they may be loosened in transit
Personnel safety practices should apply at all times
Safety glasses or face shields and gloves should be worn
Do not service glycol feed package with out disconnecting power
Close isolation valve and release pressure before servicing any components on the system
All liquids in system should be drained before servicing
Glycol feed package should be installed by qualified personnel.

13. Installation & Operation
SYSTEM WALK AROUND:
GTP Glycol Feed Package is a complete turn key system. The illustration to the left will indicate your major components. For details/technical help, please have model number and serial available when calling.
DETERMINE LOCATION:
Although the control panel is rated for outdoor use the gear pump, pressure switch and power cord should not be exposed to direct elements. In some cases, there will not be a dry indoor location that is convenient to install the glycol feed system. Some shelter, awning or shed needs to be installed to validate warranty.
Once a location has been designated for the glycol feed package, secure to a concrete pad using the mounting holes provided in the foot pads. Be sure to comply with all local codes.
Special attention should be given so that control panel, pump, low level and discharge manifold can be accessed for servicing at all times.

14. Installation & Operation
CONTROL PANEL OPERATIONS: The control panel is factory wired, tested and ready to install. Changes or modifications should only be done by qualified personnel. MAIN POWER SWITCH: Starts and stops all functions. Beware, it does not disconnect power from panel. There will be live voltage to back panel unless the glycol feed package is disconnected from power source. PUMP POWER SWITCH: The pumps switch has three positions. Hand will turn the pump no matter what the pressure is or set at as long as the float switch is engaged. The off position will stop all operations of the pump. The auto position will only turn on the pump when the pressure switch calls for it as long as the float is engaged. LOW LEVEL CIRCUIT: (Shown) The low level circuit stops all glycol feed functions and will turn on the red indicator light. The optional switch shown is part of the audible alarm circuit. This switch will silence the audible alarm but not put out the light until the condition is corrected.

15. Installations & Operation
CONNECTING TO SYSTEM:
Glycol feed package should be installed within 10 to 30 feet of system. If system is to close, it is difficult to set low pressure systems. If system is to far, pump outputs will very base on pipe size, elbows and other fittings. Glycol feed package is supplied with ½” isolation valve and should be connected to system using a minimum pipe size of ½”.
DO NOT INSTALL CHECK VALVES OR PRESSURE REDUCING VALVES BETWEEN GLYCOL FEED PACKAGE AND SYSTEM.
The installation of check valve or pressure reducing valves will cause problems with reading system pressure accurately.

16. Installation & Operation
ADJUSTING THE PRESSURE RELIEF VALVE
The Pressure relief valve on the glycol system is to prevent the system from over pressurizing when the isolation is closed and the system is left running.
Turning the pressure valve counter-clockwise will decrease the system pressure relief setting and turning the valve handle clockwise will increase the pressure setting. The standard range is from 50 to 150 PSI
If an engineer or system designer has not set the system pressure relief for you, you should have the glycol system setting above 5% to 10% higher than the main system pressure relief valve. That way in the case of system over pressure, the contents of the system will not over flow the glycol package.

17. Installation & Operation
ADJUSTING THE PUMP PRESSURE RELIEF
(Bronze gear pumps only and only of use when operating in low pressure settings)
Turning the set screw and lock nut counter-clockwise will decrease the pump internal pressure relief setting and turning it clockwise will increase the internal pressure relief setting.
This feature is a pump standard, and on our system is only needed when setting the pump in low pressure systems. Over adjustment may cause harm to the operations of the pump or cause the pump to reach maximum pressure settings.
It’s normally best to leave this alone. If you have a pump that is not performing, give us a call and we’ll be glad to help.

SETTING THE PRESSURE SWITCH
GTP Glycol Feed Packages, when specified, can be factory pre-set to your system requirements. When requested, your factory settings will be listed on label on back of instruction manual and on packing slip. If you are setting the pressure switch on site, please follow the steps below.
STEP 1) close isolation valve and open pressure relief valve.
STEP 2) Start systems in manual and adjust pressure relief valve to cut-in pressure desired. (This should be the low pressure setting)
STEP 3) Turn large adjustment nut on pressure switch out (counter-clockwise) until pressure switch is off.
STEP 4) now, turn same nut on pressure switch in (clockwise) until pressure switch is on.
STEP 5) Adjust pressure relief valve to cut-out pressure determined. (This will be the high pressure setting)

STEP 6) If pressure turn off before you could set it, turn small nut clockwise 2 or 3 revolutions and restart at STEP 2.
STEP 7) Test setting by adjusting pressure relief valve in and out of range before returning system to automatic position.
TIP: Always best to set the cut in first. Since the cut-in and cut-out work on the same pressure plate, adjusting this will change the both as you adjust it.

20. Maintenance
ROUTINE MAINTENANCE Routine maintenance in this section is referred to as checking a system once a month until a maintenance schedule can be determined. All fasteners should be checked. Maintenance and care will depend upon the usage and environment in which the glycol feed package is subject to. The following is the suggested regular maintenance checks required to keep the glycol feed system operating properly. GLYCOL PUMP The pump should be inspected for proper operation and output. Unusual noises and leaks need to be corrected immediately. Pump assembly and disassembly should only be done by qualified personnel. Wear items, like seal, carbon bearings and gears need to be inspected and replaced when needed. Contact us for assembly and disassembly. Carbon bearing pumps do not need lubrication. Check the motor for lubrication instructions. Our standard motor does not need lubrication, but some custom motors do. Be sure to check lubrication instructions in pump manual. DO NOT OVER LUBRICATE. Oil is conductive and can cause harm or electric shock.

21. Maintenance
Pressure Relief Valve
Routine Maintenance (Continued…) TANK AND PLUMBING Periodically check piping, hoses and tank fittings for leaks. Y-strainers and check valves need to be free from debris. Tank should be checked for signs of bulging and cracking. PRESSURE SWITCH The only wear item is the contacts. Make sure there are no shorts or wire connections problems. PRESSURE RELIEF VALVE Pressure relief valves need to be free from debris. Disassembling and checking the seating surface for tears and abrasion is all that needed. Improper seating of diaphragm and seal can cause valve leaks. SUCTION “Y” STRAINER Depending on environment, suction strainer should be checked periodically for debris. Clogged or dirty strainer can cause pump failure and system performance failures.
