R-410a Chillers

With the refrigeration industry at the dawn of a monumental evolutionary transformation, Whaley Products, Inc. stands firm at the forefront of water chiller system design and manufacture. WPI started the 2009 new year with an add-on facility capable of increasing production at least 200%. The added space provides ample opportunity for expansion after the 2010 product line advancement. As we all know, the gradual phase out of HCFC R-22 will begin January 1, 2010. WPI’s research and development team is in the process of fine tuning its new R-410a chiller line. R-410a Copeland Scroll compressor technology will enhance Whaley Chillers to run with higher efficiency than ever before. We are proud to introduce the following new chiller product lines:

There are many benefits of R-410A Refrigerant. R-410A is currently the leading non-ozone depleting replacement for HCFC-22 in unitized air conditioning systems for residential and light commercial units. These units are refrigerant-in-tube design, meaning these units contain no vessels such as liquid receivers, condenser barrels or chiller barrels. These components typically have test pressure ratings of 350 to 400 PSI.

R-410A has a significantly higher vapor pressure than R-22. The condensing pressure of R-410A at standard conditions is 336 PSI. This is slightly higher than our current high-pressure safety shut-off setting. An equivalent high pressure cut off for R-410A would be 553 PSI. This pressure far exceeds the pressure ratings of the components previously referenced.

Contractors and technicians need to know that R-410A can only be used in equipment designed for R-410A. It cannot be used to retrofit existing R-22 equipment due to significantly high operating pressures. Furthermore, special service equipment is required, such as a high pressure manifold gauge set, a high-pressure recovery unit, and high pressure recovery tanks. [/vc_column_text][/vc_column][/vc_row]
