Description

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 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.

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.

Kreyer Fan MR135
Make sure you plan about a year in advance since these are seasonal. Mine came in on July 20 after the barrel room endured a couple of months of heat.

A couple of surprise when you order. First- forget the instructions that come inside the unit. They're useless, in 5 languages and without anything more than cryptic pictures of other similar models.

Second, you will need a temperature switch (thermostat) which doesn't come with this unit. You can get a thermister and digital STDT switch online for about $80. Get one that is rated for at least as big as your chiller so that you can run both the chiller and this fan unit from the same thermostat.

Lastly, it would seem natural to me to mount this to the wall, which is what I had planned. The unit was designed to be mounted to the ceiling. If you want to wall mount this expect to place a rain gutter beneath it for a condensation drain. You'll need to punch new holes for the glycol lines since there are no knockouts for this.

I was a little disappointed in the air movement by the small fans but I suppose it must meet the specifications quoted by Kreyer.
