mastercontrollerboard_and_laptop_webDecember 30, 2011 – Master-Bilt has upgraded its patented master controller reverse cycle defrost (MCRCD) for walk-in refrigeration systems.

The MCRCD features a valve that reverses the flow of high temperature refrigerant through the evaporator coil, heating along its entire length and eliminating frost buildup. The upgraded version includes Web2Walk-In, a new internet-based technology program that provides complete access to the entire MCRCD system remotely. This will allow users to monitor and program all data and set points though wireless internet or a cable connection.

While maintaining a 27 per cent increase in energy savings and offering up to an 80 per cent decrease in defrost energy usage, new enhancements include high-tech features that allow users complete access of their system remotely and globally.

“With this system and upgrade, there’s no need for a service tech to climb onto a roof or enter the walk-in to monitor or adjust the refrigeration system,” says Bill Huffman, vice president of sales and marketing for Master-Bilt. “The remote offering is a must for every operation that doesn’t have someone on site 24/7 to monitor their walk-in systems.”

An Android smartphone app is also available, offering the user the same services they can access on a computer.

The upgrade will be available to existing systems as well as field replacements. Most previous MCRCD systems will be compatible with the new version, as it uses the same expansion valve, temperatures sensors and pressure transducers.

The MCRCD 2.0 system has met the LEED prescriptive of "no electric defrosting,” as outlined in the 2009  LEED for Retail: New Construction and Major Renovations guidelines.
