The models of the UN-B series are cooler condensing unit, equipped with Bitzer compressors, designed to be part of systems for commercial and industrial use.

The series is divided into 4 models: UNN-B for medium-low temperatures (temperature range from -5°C to -15°C, power consumption from 7.61 kW to 58.79 kW), UNK-B for low temperatures (temperature range from – 25°C to -35°C, power consumption from 10.83 kW to 65.22 kW) and UNX, units specifically designed for use in freezing systems (temperature range from -35°C to -45°C, power consumption from 8.18 kW to 55.28 kW).

The UN-B units are also available in a multi-purpose version: the UNQ models are units with a special construction that allows the use of the room both in medium and low temperature (temperature range covered from -5°C to -15°C and from -25°C to -35°C, power consumption from 15.31 kW to 93.58 kW).

The power range covered varies from 4 kW for freezing units with smaller capacity to over 110 kW of the most powerful models in the UN-B range, contributing, together with the construction features, to making these units refrigerating machines that are versatile and easily adaptable in terms of putting together a high-performance industrial system which is suitable to meet a wide range of requirements.

The UN-B units are assembled from a sturdy steel sheet body provided with condenser fan holder panels that can be installed both on the front side and on the unit’s lid.

A side panel, which can be easily reached even when the machine is running, houses pressure switches, service outlets and any pressure gauges.

The compact body protects a high-performance refrigerator system with reliable operation, equipped with a semi-hermetic or two-stage semi-hermetic compressor for the freezing units with crankcase resistance to be fully installed, a condenser with relevant fan with pressure switch and a thermostatic valve expansion stage.

The standard equipment of the UN-B units includes 1 or 2 compressors for all the versions of the series with a thermistor relay for the most powerful units to guarantee reliable and safe machine operation.

The equipment is completed by the solid body filter on the liquid line, liquid indicator, separator and receiver complete with relevant safety valve and adjustable minimum and maximum calibration pressure switches with automatic reset.

The UNX-B models are delivered complete with oil separator and relevant electronic pressure switch for a reduction in the quantity of oil in circulation, allowing a better efficiency of the freezing system.

The installation involves placing the UN-B units on the ground outside avoiding reductions to the room volume.

It includes the guides for the lifting forks in the lower part of the bodywork.

The anti-snow protection kit is available as an option to guarantee an optimized machine operation in the event of external positioning subject to bad weather.

The pipe connection fittings are made using pipe fittings or weld-on flanges.

The electrical panel, suitable for connection to the external control of the room, completes the equipment of a powerful and versatile condensing unit, with potential for customization through a wide range of options.
