POLAR Cat Duo (G) - Dual discharge air coolers – commercial line

Product catalog summary

General Information & Application
Fincoil POLAR Cat Duo air coolers are designed for commercial cold rooms, engine and monitoring rooms, and other spaces requiring cooling. They feature an extremely low profile, low air velocity, and noise level, making them suitable for workrooms and occupied areas. They support refrigerants such as H(C)FC, brine (G), and CO2, with capacities ranging from 1.1 to 5.2 kW.

Standard Features

Finned coil with copper tubing (ø 12.7 mm) and aluminum fins, with a fin spacing of 5 mm and a tube pitch of 35 x 30.31 mm staggered.
Casing made of polyester-coated hot-dip galvanized steel, colored white NCS 1002-4, with a patented construction for easy cleaning.
Fan motors suitable for 230/50/1 power supply, totally enclosed, impedance protected shaded-pole motors (0.42A, 0.07kW), with a minimum operating temperature of –25°C and protection class IP44.
Central junction box connection for all fans.
Hygienic and dirt-repellent surfaces, suitable for tight ceiling mounting.
Water drain connection compatible with R1” threaded and DN32 connections.
Design pressure of 26 barg, with each heat exchanger leak tested with dry air. Brine coolers have a design pressure of 6 barg.
Manual with installation and service instructions included.

Options

Electric defrost in coil and drip tray (SS).
Defrost thermostat system (Te) with defrost break thermostat and starter delay thermostat for fan, required for automatic control (tmax = -8°C).
Fan speed control (PS) with a thyristor regulator for stepless fan speed control.

Benefits

Optimized design for draught-free air throw.
Heavy-duty materials for long operational life.
Reliable performance, Eurovent certified.
Patented casing construction for easy installation and maintenance.
Energy efficient with low total cost of ownership.
Advanced product selection software available.
One full year product guarantee.
