Why Choose Remote

DRS Series Dual Compressor

Refrigeration?

By remoting all refrigerated equipment in your estab­lishment, including reach-ins, walk-ins and ice ma­chines, to a single multi-compressor system, you can
remove the heat produced by multiple refrigeration
units from your kitchen or store and reduce your air
conditioning load and energy bill. A remote system,
typically roof-mounted, also reduces noise level, ser­vice calls and extends the life of equipment.

Why Choose Master-Bilt?

Master-Bilt’s MRS series offers many advantages over
similar systems including:

• A galvanized housing with louvered doors for
condenser coil protection (optional stainless steel
nish available)

• A single roof penetration point that reduces
installation cost and chances of roof leakage

• Modular system design that simplies congura­tion, service and upgrading

• Modules that contain head pressure controls and
crankcase heaters for low ambient protection

• Condensers are also modular and are sized for
110°F ambient application

• Time clocks for both low and medium temp com­pressors for ease of service and optional defrost
scheduling

Master-Bilt also provides
options to further boost the
efciency of MRS systems.
The patented* Master Con­troller Reverse Cycle Defrost
system, a custom-designed
electronic controller for walk­in refrigeration, saves up to
27% in energy usage over an
all-mechanical system.

Master-Bilt’s optional
Master Controller
Reverse Cycle Defrost
system saves up to
27% on energy usage.

with up to an 80% reduction in defrost energy usage.

The MRS series is part of a diverse product line
including walk-ins, reach-ins and other equipment,
making Master-Bilt a single source refrigeration pro­vider. This convenience saves the hassle and expense
of shopping for multiple sources to supply each need.

The integrated reverse cycle
defrost performs a complete­ly “clean” defrost in walk-in
evaporator coils in as little
as 3-5 minutes in a freezer or
11/2 – 2 minutes in a cooler

Systems

When your requirements call for two-compressor
unit, the DRS series is the answer. An economical
complement to the MRS series, DRS models still share
many of the same quality construction and features
as well as tting the same range of applications.

DRS systems feature:

• Compressors that use a separate refrigerant circuit
providing independent function of each system

• Scroll compressors for freezer applications up to 5 HP

• Hermetic compressors for cooler applications up to
3 HP

• Common base and frame assembly

• Standard galvanized housing with louvred doors for
condenser coil protection (optional stainless steel
nish available)
The Master Controller Reverse Cycle Defrost system

is also an option on the DRS series.
