H RANGE semihermetic compressors for R22

Product catalog summary

Introduction
Dorin semi-hermetic compressors are engineered to accommodate new refrigerants and market demands, emphasizing energy efficiency, reliability, and low noise. They offer displacements from 4.42 to 244.78 m3/h and nominal capacities from 0.5 to 90 hp.

Main Characteristics

High Coefficient of Performance (C.O.P.) due to optimized fluid dynamics, efficient motors, and advanced components.
Compatible with refrigerants like R404A, R134a, R407C, R507, R407F, and R22.
Low noise and vibration through optimized mass balance and reduced gas pulsation.
Standard IP65 electrical box across all models.
Manufacturing quality certified by EN ISO9001, with UL-certified models available.

Complete Range
Various models are available, suitable for different refrigerants and applications, categorized by displacement and cylinder count.

Weight and Valves
Each model includes details on oil charge, suction, discharge, and net weight, indicating physical specifications and installation requirements.

Technical Data
Performance data is provided for both 50 Hz and 60 Hz operations, detailing displacement and power requirements for each model.

Application Limits
Specific limits apply to "CC" models, standard operations, and head fans with superheating limits. For precise limits, refer to Dorin selection software.

Notes on DTC (Discharge Temperature Control)
- DTC is installable on all H32/H7 standard compressors.
- Minimize liquid refrigerant injection by DTC to enhance efficiency.
- For special applications, contact the technical department.
- DTC can reduce performance by up to 10% depending on conditions.

Performance Data
Based on European Standard EN12900, performance data includes refrigerating capacity (Q) in watts and power input (P) in kilowatts across various evaporating temperatures.

Specifications and Models
Detailed specifications for models like H300CS, H350SB, H403CS, etc., are provided, with specific evaporating and condensing temperatures.

Key Performance Metrics
- Refrigerating capacity (Q) and power input (P) are detailed for each model at various temperatures.
- Data is presented in tables showing temperature-performance relationships.

Standards and Recommendations
Adheres to European Standard EN12900. Mixing ester oils with other oils is strongly discouraged to ensure optimal performance.

Frequency and Refrigerant
Units operate at 50 Hz using R22 refrigerant, with some data for 60 Hz operation.

Summary of Performance Tables
Tables provide a comprehensive overview of performance metrics for each model, crucial for selecting the appropriate model based on cooling requirements.
