IMPAFRI CBTARN1034 is an autonomous roof-mounted monoblock for a freezer room. It uses R455A refrigerant (A2L class, GWP 146). Select the unit according to room temperature, volume and the actual heat load.
| Room temperature | Cooling capacity | Recommended room volume |
|---|---|---|
| −25 °C | 693 W | 3 m³ |
| −20 °C | 860 W | 6 m³ |
| −15 °C | 1037 W | 10 m³ |
Manufacturer-declared ratings at +35 °C ambient temperature. These are preliminary selection values, not a substitute for a room-specific heat-load calculation.
Roof installation according to the manufacturer's ceiling-mounting drawing (p. 261). Manufacturer size series: 1. Catalog supply rating: 230 V.
Lettered dimensions A–I correspond to the 2026 manufacturer catalog installation drawing. They must not be interpreted as universal panel cut-out dimensions. Confirm the exact opening, insulation thickness and service clearances for this unit.

Factory-assembled refrigeration circuit charged with R455A (A2L), a hermetic reciprocating compressor, a high-pressure safety switch and a thermostatic expansion valve. Standard protection includes a circuit breaker; defrost uses hot-gas injection. The unit features a stainless-steel condensate drain pan with automatic condensate evaporation and a 50 mm polyurethane-insulated evaporator enclosure.
XW270K controller: remote electronic control with maximum/minimum temperature recording, the Jet Cool rapid-cooling function and a night-time operation mode.
Cold-room accessories included: LED lighting and door micro-switch connection cable. The door micro-switch itself is a separately selectable accessory if required.
The manufacturer also specifies a door-heater cable for low-temperature versions; its electrical connection must be coordinated during cold-room installation.
Optional variants list additional factory accessories shown for this model in the catalog. Confirm accessory compatibility, duct and fan dependencies and final factory surcharges before ordering. Unconfirmed voltage conversions are excluded. Optional Master–Slave control adaptation (alternating or simultaneous multi-unit operation) is available among the variants.
Exhausting condenser heat through ductwork. The standard axial condenser fan is intended for free-air discharge and cannot overcome duct resistance reliably. To extract warm condenser air through a duct, select the optional centrifugal condenser fan with horizontal or vertical discharge. IMPAFRI duct-sizing guidance allows up to 20 m equivalent duct length: each 90° bend counts as 5 m of straight duct. With two such bends, for example, no more than 10 m of straight duct remains. Depending on the connection, a circular duct adaptor and a non-return damper may be needed. Ensure sufficient make-up air and verify duct dimensions and total pressure loss against available fan static pressure.
R455A is an A2L-class refrigerant. Selection, electrical connection, installation and commissioning must be reviewed by a qualified refrigeration specialist. The cold-room enclosure, fitting, commissioning and unloading are not included in the unit price unless otherwise stated in the quotation. Made to order; lead time 4–6 weeks.
