DESCRIPTION ...
HIGH PERFORMANCE HEAT EXCHANGER
• The highly efficient and compact SKB range finned coils are designed with corrugated surface
aluminium fins (fin spacing 4.23 or 6.35 mm) and grooved internal structure copper tubes.
• The refrigerant distributors are nozzle type (nozzle factory fitted).
VENTILATION
• The SKB unit cooler line is equipped with propeller type fan assemblies, Ø 450 mm,
4 P = 1500 r.p.m., 230-400 V, 3 phase, 50 Hz, IP 54, class F, requiring no routine maintenance, with
built-in thermal-overload protection which must be connected externally to effect warranty.
• The high-output, profiled blades operate at a very low noise level.
• The fan guards conform to NF E51 190 standard.
• The option 2V5 offers a low-speed possibility which is ideal for applications with major noise
limitation requirements. Refer to the chart on correction to select a unit wired for low-speed
operation.
DEFROST
• The tubular electric heaters are fitted into pipes expanded in the finned block.
• One of these heaters is fixed under the intermediate drain pan, thus insuring equal heat
distribution for a quick and efficient defrost.
• The heaters are factory wired to a terminal block and coupled 400 V 3 phase.
• Possibility of coupling 230 V 3 phase or 230 V 1 phase.
• Defrost water is collected in the intermediate drain pan then drained through a large drain
fitting (Ø 1” G).

• An aesthetic white enamelled galvanized steel sheet casing allows for easy cleaning of the unit.
• SKB-E and SKB- C are equipped with an internal drain pan which limits condensation.
• The easily removable side panels and the hinged external drain pan allow for easy access to
the components of the evaporator (coil, fan assemblies, heater elements, connections…).
• The hinging system allows the drain pan to be taken off.
