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