Air-cooled Condensing Units (2T.2..6H.2) KP-620-2

Product catalog summary

Overview: The document outlines technical specifications for air-cooled condensing units with open drive reciprocating compressors, covering models 2T.2(Y) to 6H.2(Y). These units are compatible with refrigerants R134a, R404A/R507A, and R22, with options for other refrigerants upon request.

Key Specifications:

High cooling capacity and energy efficiency.
Compact and robust construction.
Maximum allowable pressure of 28 bar.
Compliance with EC Pressure Equipment Directive 97/23/EG.

Construction Features:

Suitable for belt drive and direct drive applications.
Features include start unloading, capacity control (from model 4T.2(Y)), crankcase heater, oil pressure switch, and electric motor.

Performance Data:

Cooling capacity based on a suction gas temperature of 20°C with liquid subcooling.
Motor speeds: 1450 min-1 (50 Hz) for belt drive; 1450 min-1 (50 Hz) or 1750 min-1 (60 Hz) for direct drive.

Additional Information: Further details are available in the KP-520 (Open Compressors) and DP-300 (Liquid Receivers) leaflets, and the BITZER software.

Type Designation Explanation: Includes explanations for type designations, such as 'S' for belt drive and 'KG' for direct drive.

Performance Tables: Detailed tables show cooling capacities at various evaporating temperatures and motor speeds for different models.

Specifications: Detailed specifications for models like LH135/4H.2-KG, LH135/4G.2-KG, and LH135/6H.2-KG, covering parameters such as evaporating temperature, cooling capacity, motor pulley diameter, displacement volume, and driving motor power.

Procedures: Outlines procedures for direct and belt drive configurations, specifying motor speeds and adjustments for compressor speeds, and the use of additional cooling or larger condensers for optimal performance.

Standards and Recommendations: Adheres to DIN 7753 standards for V-belts and recommends a pressure relief valve according to VGB20. Specifies electrical requirements for models, such as 230V ∆ / 400V Y / 3 / 50 Hz ±10% for the LH135 series, with an incorporated winding thermostat for safety.

Dimensional Drawings: Provides dimensional drawings for direct and belt drive systems, with detailed measurements and connection positions for suction valves, discharge lines, and refrigerant outlets.

Key Data from Tables: Tables present cooling capacities across evaporating temperatures from 10°C to -40°C, maximum refrigerant charge for different refrigerants, and the weight of each compressor model.
