Master-Bilt Upgrades Master Controller Defrost System


NEW ALBANY, MISS.—Master-Bilt’s patented Master Controller Reverse Cycle Defrost for walk-in refrigeration systems has been upgraded. While maintaining a 27 percent increase in energy savings and offering up to an 80 percent decrease in defrost energy usage, a new enhancement over the current system includes high-tech features that now allow users to have complete access of their system remotely and globally.

The Master Controller Reverse Cycle Defrost System (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. Now, it’s been upgraded to include 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.

An app is also available through Android smart-phones that will provide the user with the same services as a computer. Web2Walk-In provides a user-friendly program to insure overall constant access to data and allows the users to improve refrigeration system performance and avoid service issues.

Maintenance-Friendly System

“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.”

This upgrade will be available to existing systems as well as a field replacement. Most previous MCRCD systems will be compatible with the new 2.0 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” in the 2009 outline of LEED for Retail: New Construction and Major Renovations.
