The models of the UN-D series are walk in cooler condensing unit, equipped with Dorin compressors, designed to be part of systems for commercial and industrial use.
The series includes 2 models: UNN-D for medium-low temperatures (temperature range from -5°C to -15°C, power consumption from 7.61 kW to 58.79 kW) and UNK-D for low temperatures (temperature range from -25°C at -35°C, power consumption from 31.28 kW to 65.22 kW).
The power range covered varies from 8 kW to over 100 kW in the most powerful models in the UN-D 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-D 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 bodywork protects a high-performance refrigerating system with reliable operation, equipped with a single or double semi-hermetic compressor in the UNK 86000 and 88000 units, with associated crankcase resistance, condenser with relevant fan equipped with a pressure switch and a thermostatic valve expansion stage.
The standard equipment of the UN-D units includes 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 pressure switches with automatic reset.
The installation involves placing the UN-D 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.
An anti-snow 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.
