PRODUCT FEATURES 

SCT Evaporators are available in three models each having a 

wide range of capacities and material options. 

SCTM UNIT COOLERS 

SCTM Models are designed for low, medium and high temperature 

applications. These models feature axial fans and 

many end user oriented features such as: 

One to Five Fan Models 

Capacities from 2 to 46 TR 

Hinged Fan Panels 

Sloped Top Panels 

Dual Sloped Full Coverage 

Drain Pans 

SCTW WORKROOM UNITS 

Low velocity air units for processing rooms. These models 

feature axial fans and many end user oriented features. 



Hinged Access Panels 

Sloped Top Panels 


Drain Pans 

SCTD LOW PROFILE UNIT COOLERS 

Dual coil models for low, medium and high temperature 

applications in rooms with low ceiling height requirements. 



Hinged Fan Panels 


Drain Pans 

MATERIALS OF CONSTRUCTION 

COPPER COILS 

SCT Evaporators are equipped as standard with Copper tubing 

and Aluminum fins. 

The round tubing is fit into the Aluminum fin plate and 

hydraulically expanded. This procedure provides more consistent 

contact between the tube and the fin plate than 

mechanical expansion. The entire coil is then pressure tested 

to 400 psig. Lastly, the coil is evacuated and charged with low 

pressure Nitrogen prior to shipment. 

The Copper tubes are available in 5/8" OD. Coils are built in 

3 and 4 fpi as standard. Variable fin spacing is available as an 

option. 

CASING 

SCTM Evaporators 

Standard construction of the casing and drain pan is from 

G-235 Hot Dip Galvanized Steel with an option for Type 304 

Stainless Steel 

SCTW Evaporators 

Workroom units are manufactured with Type 304 Stainless 

Steel casing panels and pan cover. The fan motor base, inner 

pan and shipping/installation supports are constructed from 


Stainless Steel.

PERFORMANCE FACTORS 

The capacity of SCT Evaporators is based on R22 refrigerant at a +20°F coil temperature at 0” ESP. Ratings are provided wet and 

frosted with either recirculated flooded or DX feed. The heat rejection capacity of SCT Evaporators must be adjusted for different 

refrigerants and feed conditions. Multiply the factor listed in table below by the appropriate coil performance to obtain the new 

capacity rating for the specific application. The factors vary based on refrigerant and coil temperature.
