Refrigeration Compressor – Full English Product Introduction

1. Product Overview

Our refrigeration compressors are core power units for all vapor-compression refrigeration systems, covering reciprocating piston, scroll, semi-hermetic screw, inverter variable-speed models with complete HP range from 1HP to 390HP. Engineered with 30+ years of refrigeration manufacturing experience, they deliver stable cooling capacity, outstanding energy efficiency and ultra-long service life for commercial & industrial cold storage, freezing, food processing, supermarket display cabinets, pharmaceutical low-temp storage, ice plants and process cooling systems.

Compatible with mainstream refrigerants: R404A, R507A, R134a, R407C, R290 and other low-GWP eco-friendly refrigerants, fully compliant with EU CE, UL and international environmental standard

2. Core Key Features & Advantages

① High Energy Efficiency & Cost Saving

· Optimized rotor / valve plate design reduces internal compression loss; inverter models cut power consumption by up to 30% under partial load

· Screw models adopt 5/6 asymmetric rotor profile with built-in high-efficiency oil separator (separation rate ≥99.85%), less oil circulation improves heat exchange efficiency and lowers operating cost.

· Wide capacity adjustment range (10%–100% stepless regulation), matches fluctuating cooling demand perfectly to avoid idle energy waste.

② Superior Stability & Ultra Low Noise

· Heavy-duty cast iron body, precision crankshaft and multi-point bearing pairing minimize vibration during continuous operation; running noise controlled within 48–58dB.

· Semi-hermetic fully sealed structure prevents refrigerant leakage, no frequent gas refilling; integrated suction filter blocks impurities to protect internal components.

· Complete multi-layer safety protection modules: overheat, phase loss, reverse rotation, high/low pressure, overload and liquid hammer protection, auto alarm & shutdown for fault prevention.

③ Robust Durability & Low Maintenance

· Wear-resistant alloy moving parts, thickened copper pipeline and anti-corrosion coating adapt to high-humidity, dusty industrial workshops and cold room environments.

· Modular integrated design with built-in filter, sensor and stop valves; quick disassembly for inspection and part replacement, cutting maintenance time by 40%.

· Fewer vulnerable parts vs traditional compressors, extending service life up to 15+ years under standard working conditions.

④ Smart & Flexible Application

· Optional digital PLC control panel with real-time monitoring of temperature, pressure, current and running hours; supports remote data reading & parameter adjustment.

· Multiple voltage options: 380V/400V/440V 3-phase 50/60Hz, compatible with global power grids.

· Single unit or multi-parallel rack assembly available; customized double-stage compression versions for ultra-low temp (-45℃ ~ -70℃) deep freezing scenarios.

⑤ Eco-Friendly & Safe Certification

· Supports low-GWP natural refrigerants to meet global carbon neutrality requirements.

· All models pass CE, UL, RoHS industrial safety certifications; explosion-proof optional versions for chemical & hazardous cold storage.

3. Wide Application Scenarios

1. Food Industry: Cold storage warehouse, quick-freezing line, seafood deep freezer, meat & dairy preservation, supermarket chiller & freezer cabinets

2. Pharmaceutical & Biotech: Vaccine ultra-low temperature storage, laboratory constant-temperature equipment

3. Industrial Process: Factory cooling water chiller, chemical raw material low-temp storage, injection molding cooling

4. Commercial Facilities: Ice rink, hotel central air conditioning, logistics cold chain transport refrigeration units

4. Technical Support & Warranty

· One-stop solution: Compressor single unit, condensing rack unit, system matching design & technical drawing support.

· Global after-sales service network, fast spare parts supply.

· Standard 1-year full-unit warranty; key core components (crankshaft, rotor, motor) enjoy extended 3–5 year warranty.
