2011 Munters Sales Meeting | Dehumidification for Food Applications Standard Desiccant Dehumidification The dehumidifier is based on Munters unique Honeycombe® sorption drying wheel: Process air passes through the drying wheel and leaves the dehumidifier as dry air Heated reactivation air collects the moisture absorbed by the drying wheel and leaves the dehumidifier as wet air Air supplied to area has dewpoint below freezing Supply air acts as a sponge 2011 Munters Sales Meeting | Dehumidification for Food Applications March 7, 2011

2011 Munters Sales Meeting | Dehumidification for Food Applications Food Safety & Inspection Service (FSIS) Regulations 9 CFR § 416.2(d) Ventilation states, “Ventilation adequate to control odors, vapors, and condensation to the extent necessary to prevent adulteration of product and the creation of insanitary conditions must be provided.” Regulations: Observations and Impacts This regulation does not provide a solution or a recommendation, just the need to solve the problem. Burden is placed on the processor to decide how to proceed In fact….the regulation states, “Ventilation adequate to….” which may cause a greater problem if applied literally and without discipline Adding ventilation may actually increase “sweating” as large amounts of unconditioned outside air can condense on cold surfaces 2011 Munters Sales Meeting | Dehumidification for Food Applications March 7, 2011

2011 Munters Sales Meeting | Dehumidification for Food Applications Typical Ventilation Layout Historically the plant philosophy has been to ventilate to an excess. Exhaust fans in the Pick/Scald area pull air through the plant, increasing infiltration of raw outside air. This is one of the root causes of the problem… and a focal point for its resolution. 2011 Munters Sales Meeting | Dehumidification for Food Applications March 7, 2011

2011 Munters Sales Meeting | Dehumidification for Food Applications Notes Be careful when discussing drying, make sure they know there is no product drying (yield is very important) Don’t bid what you know is wrong, let’s talk first Must sell the end user Don’t push desiccant where it does not make sense! Be credible. Talk the talk, understand the application or you will loose credibility Very competitive Market (pricing), they make less than 1 cent per pound profit Once a rental goes in, it will not come out until permanent equipment is installed It’s a very open market, having them talk to one of our existing customers, also, some of our customers will open up their plant for new customers to view Everyone has worked for or with everyone, good news travels fast, bad news travels faster!

2011 Munters Sales Meeting | Dehumidification for Food Applications The Munters Solution Eliminates infiltration load: Example: If you have a -25 spiral freezer and plant ambient conditions of 75 F DB at 60% RH. Freezer inlets are 2’ x 4’ (assume 150 FPM infiltration) Using gr/hr / 7000 = (CFM) * (4.5) * (delta gr/lb) gr/hr / 7000 = (2,400 CFM) * (4.5) * (78.1 – 1.3) Lb / hr = 118.5 Positive Pressure in the freezer aids in product load 2011 Munters Sales Meeting | Dehumidification for Food Applications March 7, 2011

2011 Munters Sales Meeting | Dehumidification for Food Applications Notes We are handling the infiltration load. Product load is a lot more difficult to control, once the moisture enters the freezer, it’s there. Don’t promise “no defrost cycles”. They can’t run 24/7, 365 days without a defrost cycle (or shut down). Find out what the customer currently experienced, what they are looking for (do they get better performance in the winter time) Try to determine the infiltration load and product load 2011 Munters Sales Meeting | Dehumidification for Food Applications March 7, 2011

2011 Munters Sales Meeting | Dehumidification for Food Applications Process Freezer Benefits Reduction in defrost cycles in freezer Reduction in ice on inlets and outlets of conveyors More throughput Coils working more efficiently Able to stay in production 2011 Munters Sales Meeting | Dehumidification for Food Applications March 7, 2011
