There are two main applications areas :-

• High Temperature : such as store rooms and occupied areas, using either propeller or ducted axial fans for low face velocities, low noise and high efficiency.
• Low Temperature : such as cold storage or blast freezing, using either propeller or ducted axial fans for high velocities and high air throws where low noise levels are not required.

Standard features of the range include :- 

• 4 heights available, SM16,20,24,30
• 'S' fin with large secondary cooling surface
• 4mm, 6mm or 8mm fin spacing
• Propeller or ducted axial fans
• 218kg (SM161) to 1389kg (SM304)
  

Optional Extras

• alternative fin materials : vinyl coated aluminium, copper, electro-tinned copper
• electric defrost
• glycol circuiting
• 10mm or 12mm fin spacings
• hot gas defrost (coil & draintray)
• peripheral heaters (for below freezing)
