Product catalog summary

Introduction
Frascold celebrates its 75th anniversary, showcasing its evolution from 1936 to the present, marked by technological advancements and global expansion in the refrigeration and air conditioning industry. The company emphasizes innovation, strong customer relationships, and maintaining a leading market position.

General Overview of CXH Series Compressors
The CXH series compressors are versatile, designed for refrigeration, air conditioning, and heat pump systems. They are recognized for reliability, minimal maintenance, noise reduction, and high performance at partial loads. The series includes 27 models with volume displacements from 199 to 912 m3/h, supporting refrigerant needs up to 1600 kW.

Main Features

High-efficiency electric motors with part winding start (PWS) for CXH0 and CXH5 models, and star-delta-start (SDS) for CXH9 models, with integrated PTC sensors for thermal protection.
A sophisticated capacity control system ensures high efficiency at both full and partial loads, with precise regulation even under critical conditions.
A three-stage oil separator minimizes lubricant circulation in the system.
The oil management system includes an accessible cartridge-type oil filter, with optional sensors for monitoring.
Innovative bearing configuration protects against counter-rotations, reducing noise and increasing lifespan.
Compressors can be driven by an inverter within a frequency range of 30 to 70 Hz.
Double-walled rotor body and screw profile design contribute to reduced noise and compact size.

Standard Equipment and Options

Standard equipment includes a discharge valve, suction flange, capacity control, check valve, oil heater, oil sight glass, service valve, and electronic protection module.
Optional features include a suction valve, economiser connection valve, optoelectronic oil level switch, oil flow switch, differential oil pressure switch, electronic alarm management module, and rubber vibration absorber kit.

Model Designation
The model designation provides information on the compressor series, motor size, displacement, and oil type, facilitating easy identification and selection.
