Unit Description
General Description
The Spectrum DE is a diesel powered,
multi-temperature refrigeration system. The unit
provides heavy duty temperature control for
multiple compartment trailers. The Spectrum DE
30-2 unit is equipped with a dual evaporator. The
unit mounts on front of the trailer. Two separate
temperature controlled trailer compartments can
be used without the need for a remote evaporator.
Each side of the dual evaporator serves one side of
the trailer, which is split longitudinally. The
compartment to the control box side of the unit is
called Zone 1. The compartment to the
compressor side of the unit is called Zone 2. The
compartments can carry fresh, frozen, and/or dry
products. Each compartment can be quickly
changed to carry any type of product.
In the Spectrum DE 30-3 a remote Spectrum
Evaporator is added to provide a third
compartment (Zone 3).

Host Unit
The host unit contains the diesel engine, the
compressor, the condenser, the dual evaporator
and the control box. The unit is equipped with a
Smart Reefer Multi-Temp µP-IV Microprocessor,
which controls the operation of the host unit, the
dual evaporators, and remote evaporator (where
used). Refrigeration lines and wire harness
connect the host unit to the remote evaporator
(where used).
The host unit mounts on the front of the trailer
with the dual evaporator extending through a hole
in the front wall into separate compartments
inside the trailer.
Units manufactured after the third quarter of 2004
are being built with plastic skins.
