Cool your cellar using your existing glycol system. Save energy and money! These units work under the same principles as standard refrigeration but use cooled glycol that you already have instead of cooled refrigerant gas, eliminating the need to have a separate refrigeration system. It is a fantastic use of your glycol system for a majority of the year when typically glycol systems are on but are being sporadically called upon. Glycol systems do need to be sized to accommodate both these fan units and peak duty during the crush to be able to accommodate all tasks at once.

Glycol from your main glycol chiller is recirculated through these fan units. Aluminum fins act as heat exchangers drawing heat out of your room as the fins are cooled by the glycol. If you have a Kreyer chiller/heater you can even heat a space in cold weather environments.

The heat exchangers inside the units are made from corrugated aluminum fins and internally grooved copper tubes. The white ABS casing looks great. Because of its rounded corners it has no water retaining areas favorable to germ development. Units are outfitted with stainless steel screws and show no sharp, cutting edges.

The MR series is quieter than the SD series but not as robust in construction.

Fan Unit Temp Control Upgrades:

  • 1/2 in. Solenoid Valve - Allows or blocks flow of glycol through the fan unit.  Needs to be connected to a Controller to function.  A filter is recommended to protect the solenoid.
  • 1/2 in. Solenoid Filter - protects the solenoid valve from any particulate or sediment.
  • Glycol Fan Control Unit - Set a specific temperature on this controller and it will open and close the solenoid valve.
  • Solenoid Connection Cable - This 2 meter long cable is required to connect the Solenoid Valve & Control unit.

  • Will cool well insulated spaces up to 1750 cubic feet while drawing 1/3 Ton of cooling power
  • Single Fan Unit (pictured is 3 fan unit)
  • 220V connection required to run fan
