Features/Applications Century Refrigeration s WIBR Series Unit Coolers are designed for in between the rails commercial and industrial freezer and cooler applications at or above -30 F. The WIBR Series Unit Coolers utilize a configuration of fans, motor horsepower, coil circuiting, and blade configuration to meet your specific project needs. The following features are standard on each WIBR Series Unit Cooler: 24 models from 18,000 to 185,000 BTUH Fin spacing available at 4 or 6 FPI Aluminum plate fin coil at 4, 6, or 8 rows Insulated drain pan Adjustable defrost termination/fan delay on electric and hot gas defrost models Available in air, electric, or hot gas defrost configurations Top air discharge arrangement with V air diffuser Standard mounting configuration is ceiling hung 28 diameter fan blades with 1, 2, 3, or 4 fans 1/2 HP fan motors with 115/60/1, 208-230/60/1, 208-230/60/3, and 460/60/3 voltages In Electric Defrost and Hot Gas Defrost models, condensate drain lines must be adequately heat traced in rooms below freezing. Support piping adequately with suction line P traps at unit. Locate liquid line solenoid close to TXV. Use externally equalized TXV. Available Options Units circuited for water or glycol solutions Mounted non-fused fan motor disconnect switch standard with auxillary contact for liquid solenoid Mounted non-fused heater disconnect switch Mounted or shipped loosetxv Mounted or shipped loose electronic expansion valves Various fin materials, coatings and casing arrangements available for corrosive atmosphere applications Stainless steel hardware, fasteners, and/or housings Motor and fan blade combinations for hazardous duty applications ECM or VFD compatible motors can be supplied with overloads and single-point wiring connection ECM motors for 115-208-230/1 phase applications to comply with federal standards.

Construction Cabinet Cabinets are made of heavy-gauge, rust-proof, smooth finish aluminum housing. All hardware is corrosion resistant. Full die-formed venturies minimize noise with maximum air throw. Fan guards are heavy-gauge wire basket-type coated for corrosion protection. Coil Coils are copper tube, full-collared die-formed aluminum plate fin and tube sheets. Tubes are mechanically expanded for maximum heat transfer. Coils are leak tested at 350 PSIG under water. Solder distributors have removable nozzles. Each nozzle is sized for the specified refrigerant and temperature range. All coils use an external equalized expansion valve. Fans Fans are 28 inch fiberglass reinforced polypropylene blades with steel hubs that are statically and dynamically balanced for smooth operation. They are selected for maximum air throw. Motors Motors are permanently lubricated for reduced maintenance time and costs and suitable for low temperature applications. Motors are heavy duty, high efficiency, full ball bearing and have internal thermal overloads to protect against over-amperage and overheating. Motors are suitable for single-point group fusing. Fan motors are pre-wired to terminal blocks. Refrigerants Coils are designed for use with many refrigerants. Defrost Electric Defrost models include pre-wired terminal blocks and low-watt density heaters that are housed internal to the coil for a rapid and efficient defrost. Lower coil heaters and drain pan heaters help provide fast and reliable condensate drainage. Standard operating control includes an adjustable defrost termination with fan delay. Hot Gas Defrost models include an auxiliary side port connection on the distributor, insulated drain pan with a hot gas loop in the pan, and a check valve shipped loose. An adjustable defrost termination/fan delay switch is also provided with this option for temperature termination of the defrost period. Mounting Century offers ceiling mounting for each WIBR Series model.
