IMPAFRI SBHCQRG30075 split refrigeration system with cubic evaporator

A matched split system for product storage

IMPAFRI SBHCQRG30075 is a split system for standard cold rooms. This system separates the indoor evaporator from the heat-rejecting condensing unit, allowing the cold-room layout and outdoor ventilation/service space to be planned independently. The factory-matched package helps coordinate the refrigeration equipment.

Practical benefits

• Evaporator suited to room geometry: a low-profile unit preserves ceiling space; a cubic evaporator should be assessed where directed airflow is needed through a longer or more heavily loaded room. Leave circulation and service clearances.
• Separate heat rejection: allows the condensing unit to be positioned outside the room. Its location must admit fresh air and remove the heat discharged by the refrigeration circuit.
• Factory refrigeration components: include thermostatic expansion and solenoid valves, pressure protection and electronic control. Site pipework and installation are planned separately.

This model uses a cubic evaporator. Use the temperature-specific ratings in the specification when sizing the room.

Range configuration and selection limits

Select freezer equipment at the required negative-temperature point and positive-temperature equipment at its actual room setpoint. The catalogue volume is an initial selection estimate. Frequent door openings and warm incoming stock can require more capacity in a room of the same volume.

Condensing unit location and installation

This model has a centrifugal condensing-unit fan for ducted rejection of warm condenser air. Size the duct against the actual airflow and available fan pressure, not the connection dimensions alone. Provide sufficient make-up air.

How to size this model

Published capacity points for this factory model: −25, −20, −15 °C. In the specification, compare capacity and estimated room volume at the same room temperature. Cooling capacity is not electrical input. Provide internal room dimensions, insulation, ambient temperature, daily product load and incoming temperature, door-opening frequency and the proposed pipe route. An unpublished operating point must not be substituted by a rating at a different temperature.

Supply scope and documentation

Supply covers the factory condensing unit, evaporator and range-specific controls. The cold-room enclosure, site copper pipework and insulation, electrical installation and commissioning are planned separately. Pre-charge for 10 m does not itself mean that pipes or all interconnecting cables are supplied.
