Technical Specifications Overview

Cooling Capacity and Power Input:
The document provides detailed specifications for various models (10 to 602) of cooling units. Each model is characterized by its cooling capacity, expressed in kW, Kcal/h, and tons, and its power input in kW. The cooling capacity is provided for two different conditions: (1) with chilled water temperature inlet/outlet at +20°C/+15°C and air temperature on the condenser at +25°C, and (2) with chilled water temperature inlet/outlet at +12°C/+7°C and air temperature on the condenser at +32°C.

Compressors and Fans:
Models are equipped with either hermetic "scroll" compressors (models 10 to 151) or semi-hermetic compressors (models 201 to 602). The number of compressors and fans varies by model, with larger models having more components to handle increased capacity.

Air Flow and Motor Specifications:
Total air flow is measured in m3/s, and motor power is specified in kW. The rotation speed of fans is given in rpm, with most models operating at 930 rpm.

Evaporator and Water Pump:
The evaporator's water content is specified in dm3, and the nominal power of the water pump is given in kW. Water flow rates are provided for both nominal and maximum conditions.

Sound Power Level:
Sound power levels are specified in dB(A), with values ranging from 77 to 88 dB(A) depending on the model.

Dimensions and Weight:
Each model's dimensions (length, depth, height) and weights (shipping and operating) are detailed, indicating the physical size and mass of the units.

Construction and Materials:
The units are constructed with galvanized or stove-enamelled sheet steel, with components like the base frame, internal metal works, and panels designed for durability and ease of installation.

Control and Safety Features:
Units are equipped with a microprocessor control system that manages temperature regulation, compressor operation, and safety features such as anti-freeze protection and alarm systems. The control panel includes a digital display and options for remote operation.

Refrigerant Circuit:
The refrigerant circuit is made of braze-welded copper tubes and includes safety devices. For larger models (502 and 602), the circuit is double and independent.

Additional Features:
Units include features like a thermostatic expansion valve, "no frost" evaporator, high and low-pressure switches, and a centrifugal pump for water circulation.
