Energy Saver Program

Because energy savings is an ever-increasing concern, Master-Bilt strives to make our equipment as efficient as possible. That’s why we initiated our Energy Saver program to help you quickly identify features that serve your efficiency needs. Below is a list of features and options included in the program.

FEATURE

ENERGY-SAVING FUNCTION

WHERE USED

Demand defrost

Initiates electric defrost heaters only as needed

 

As part of the optional Master Controller electronic control system on walk-ins

Electric expansion valve

 

Highly efficient valve eliminates need to maintain a high head pressure (head pressure control valve eliminated also) allowing a lower head pressure and condensing temperature. A compressor operating at a lower condensing temperature yields higher capacity with less energy input.

As an integrated part of the optional Master Controller system for walk-ins

Reverse cycle defrost

 

A reverse cycle valve reverses the flow of high temperature refrigerant through evaporator coil, heating along its entire length and eliminating frost buildup. Results in an 80% decrease in defrost energy usage as well as a major reduction in defrost time.

An option used in conjunction with the Master Controller on walk-ins

T8 electronic and LED lighting

 

Both types introduce less heat into the refrigerated space which reduces the workload on the refrigeration system's compressor. The less the compressor operates, the more energy is saved. LEDs also save money because they last longer than fluorescent bulbs.

LEDs optional in select cabinets, T8 lighting with electronic ballasts standard in numerous cabinets and glass door walk-in freezers

MBWA-1 digital alarm/light management system

 

Door open alarm prevents door from being left open. Optional light management system automatically turns off lights after a programmed interval.

An option on walk-in coolers and freezers

Glass Sentry II

The Glass Sentry II anti-sweat control module is designed to save energy by turning off glass door and frame heaters when no door heat is necessary.

An option on glass door walk-in coolers and freezers

Permanent Split Capacitor (PSC) Fan Motors

Amount of torque and current required to start PSC motors is low, making them more efficient. PSC motors run cooler, reducing heat load to refrigerated space which makes the compressor run less.

Optional on single phase walk-in unit coolers and standard on condensing units

5" and 6" thick panels

Thickness of panels produces a higher R-factor and energy efficiency required by California Energy Code

An option on walk-in coolers and freezers

MRS & DRS multi-compressor remote refrigeration systems

Since these systems are remote, the heat produced by multiple condensing units is removed from the kitchen or sales space reducing the air conditioning load and energy bill

Walk-ins and cabinets with remote refrigeration systems

Scroll compressors

Approximate 20% increase in energy efficiency

An option on walk-in cooler and freezer refrigeration systems
