The models of the TH-D series are multicompressor air-cooled condensing units equipped with multiple semi-hermetic compressors, specifically silenced for external installation for industrial use in residential areas.

The series is divided into 2 models: THN for operating temperatures from 5° to -20° with nominal consumption from 33.07 to 138.10 kW and THK for operating temperatures from -15° to -40° with nominal consumption from 26.25 to 137.48 kW.

All models have been built around a base frame made of pre-painted metal sheets with condenser, equipped with a thermal or pressostatic speed variator, placed vertically on one or two sides of the unit and with the fans placed on the cover panel of the frame.

The compressors compartment, isolated with simple ashlar to reduce its noise level during operation, is separated from the condenser through a bulkhead that still allows internal ventilation.

The three compressors are mounted in parallel having in common the delivery and suction manifold, and fixed to the base frame through rubber blocks which avoid potential vibration of the unit during operation.

The construction type and the semi-hermetic compressors, available in various models for a power range covered from 16.5 to 99 kW make the TH-D flexible and safe machines.

Each compressor is also equipped with the relevant taps and anti-vibration dampers in both the delivery and in the suction phases and a check valve on the gas delivery pipe.

The oil is managed by a separator and oil equalization connected by a manifold mounted on the compressor lights and a check valve on the gas delivery pipe and the delivery and suction anti-vibration dampers.

The refrigeration system is completed by liquid receivers, equipped with a safety valve, a dehydrating filter, liquid level alarm, sight glass and shut-off taps. As a standard feature, with a view to increasing efficiency and safety, the TH-D units are equipped with double minimum and maximum pressure switches for general and emergency use that are adjustable and have an automatic reset, 3 pressure switches for compressor control in emergency operation, one minimum pressure detection probe, for suction capacity control, and a double maximum and minimum pressure gauge.

The standard installation involves placing the TH units on the ground outside avoiding reductions to the room volume.

The TH-D units are monitored and customized in operation by means of an electrical panel placed on the side of the body, while the control unit manages all of the settings centrally.

The panel protected by the closing panels includes the disconnector, the power distribution system and the protections for the compressor and fan via motor protection switches and safety fuses respectively.

Four emergency lights, fan block and pressure switch block and 3 0/1 selectors for the compressors complete the profile of a reliable, safe and versatile condensing unit in terms of putting together a complete industrial refrigeration system.
