Caleffiair separatorrebuild Kit

I purchased this glycol pump as part of the build your own, which included the manifolds pump, expansion tank, air separator and basic plumbing supplies. I was very happy with how everything arrived together and the install was straightforward just from looking at the pictures. The glycol pump makes it easy to charge the system, and took a lot of the guesswork out of setting it up. My garage now has toasty warm floors.

1/2" Union Dual check backflow preventer with atmospheric vent is backordered and will ship as soon as it is back in stock.

This dual check backflow preventer with intermediate atmospheric vent is designed to protect drinking water systems from the return, caused by backsiphonage or backpressure, of contaminated fluids.

COMMERCIAL & PROCESS: Whether you are using a Bell and Gossett CRS coalescing air and dirt separator, a Bell and Gossett Rolairtrol air separator, or a low velocity buffer tank; the placement of the air separator in a chilled water system is on the secondary return. The air separator in a heating system is on the secondary supply.

RESIDENTIAL: Whether you are using a Bell and Gossett EAS coalescing air separator, a Bell and Gossett IAS inline air separator, or a low velocity buffer tank; the placement of the air separator in a chilled water system is on the secondary return. The air separator in a heating system is on the secondary supply.

R. L. Deppmann is offering another series of seminars, this fall, which are centered on “Energy Savings and ASHRAE 90.1 and 189.1 standards”. During a couple of the first 7 seminars, the question of the air separation location sparked a short discussion. Let’s review the response in this Monday Morning Minute.

This is the second unit I’ve installed as the first one, installed two winters ago in another building is working so well. No problems, easy to install. Both systems are hydronic floor heat and these units work great. Just fyi…….going to electric now works out cheaper than the original propane costs. Like that it’s Canadian made.

I bought these to replace some wax actuators from my old system. Those were inconsistent (each moved a different amount) and had huge in rush power requirements. These have low power requirements and appear to be very consistent.

This dual check backflow preventer with intermediate atmospheric vent is designed to protect drinking water systems from the return, caused by backsiphonage or backpressure, of contaminated fluids.

Entrained air is released from the water or Dow glycol heat transfer fluid as the temperature increases. (See chart below). Entrained air is also released at the lowest pressure in the system. So as a general rule, the air separator performs best in the warmest water and at the lowest pressure point in the system.
