New Options for DryCool Products Presented by: Scott McGinnis Regional Sales Manager LEED® Associate

What market has asked for Digital Scrolls, even though they don’t always know why Discharge Air Dew Point control Limits of Desiccant Wheel Reheat Post cooling options More efficient HCU-ERV with less restrictions Lower Dewpoints No RA CFM limitations (old 70% rule) Plate Exchangers vs. wheels Larger Sizes (Greater than 16,000)

We have all that available All the new options and layout are available Require help form your AE Pricing Performance Layouts As these become more popular will be integrated into the Air Manager selection software

Digital Scroll Option Very popular technology Keeps compressor motor running Allows for part load (~10% minimum) Provides Modulating DX coil Munters has been experimenting with effect on Dh Wheels Munters also tested Danfoss VFD Proved too costly for benefit

First On / Last Off = Standard Scroll Must have Reheat

B compressor is digital Programmed to modulate up and down for two reasons 1. Discharge Air Dew Point control: Set a leaving air dewpoint and maintain that DryBulb will fluctuate 2. Set a maximum leaving discharge air temp Set at 75F to May over dry the air, but will limit the discharge air so not so high

Auto Mode – DH with SA maximum limit

Digital in B Energy Recovery Indoors without remote ACCU DryCool ERV

DryCool ERV B A B compressor is the Digital Always have 50% dehumidification Modulate then from 60% up to 100% Same control options Discharge Air Dewpoint Max Sensible Temp 82F/54 dp 79F/52dp 77F/50dp A B 75F/48 dp 72F/47 dp

Digital Scroll Availability and Adds 15 tons digital is the largest we will use right now Up to all 60 ton, 4 compressor machines Available on all HCUs, expect the 1680 DryCool ERV up to 1648 Split B compressor into 2 independent circuits (2 x 12 tons) DryCool Standard Add ALC controller Price add for Digital Comp and electronics DryCool ERV Add only for Digital Comp and electronics

HCU-ERV or “3” Fan ERV Take a DryCool Standard Air Cooled or Water Cooled System Reactivation Fan with OA inlet for Reactivation Standard CFM/Ton ration for Attach an enthalpy wheel Module to the back end Enthalpy Wheel EA Fan Recirculation Damper Actually the first HCU-ERV produced

ERV DryCool

3 FAN ERV No 70% RA rule, just standard enthalpy wheel rules ACCU or WCCU Lower dewpoints Better Staging with 4 compressors and digital options Uneven RA airflow Lower Winter Energy as there is no Reactivation Air in winter Works for all DryCool Standard Models

New 3 Fan Unit: New Design, on case by case basis Condenser Coils A: Standard B: Digital 3 2 1

New 3 Fan Unit: New Design, on case by case basis No 70% Rule, uneven airflows thru Enthalpy Wheel No Winter Pressure drop penalty Lower Dewpoints 2 compressors A = Standard B = Digital So, adds the discharge air dew point and max dry bulb control

New 3-Fan
