Product Description
Refcomp SP6H3700 SP6H370E 37HP High Temperature Semi-Hermetic Compressor
Product Features
Flexible Capacity Regulation
Designed for demanding refrigeration systems, the SP6H3700 semi-hermetic compressor features a solenoid-controlled energy regulation system offering 100%, 66%, and 33% capacity steps. This multi-stage output matching allows the compressor to adapt smoothly to fluctuating cooling loads, reducing frequent motor cycling and lowering energy consumption under part-load operating conditions.

Optimized Motor & Cooling Architecture
The custom-engineered motor allows this semi-hermetic compressor to operate seamlessly across different voltages and frequencies (400V/50Hz and 460V/60Hz PW). Built with internal flow channels that direct suction gas across the motor housing before entering the cylinders, the design maintains low operating motor temperatures, ensuring stable performance across multiple refrigerants including R22, R407C, R134a, R404A, and R507.

Heavy-Duty Bearings & Mechanical Assembly
Equipped with precision-machined journal bearings and a balanced crankshaft, the semi-hermetic compressor minimizes mechanical friction and radial wear. The optimized piston and connecting rod linkage, paired with wear-resistant bushings, reduces gas pulsation and structural vibration, delivering smooth running characteristics and prolonged mechanical service life.

Integrated Suction Filtering & Safety Protection
To safeguard internal components, this semi-hermetic compressor incorporates an outer-accessible high-density suction filter that removes gas-stream impurities while remaining easy to service or replace. An internal pressure safety valve balances high and low pressure sides during abnormal conditions, while the integrated INT6902 motor protection module guards against thermal overload and phase faults.

Frequently Asked Questions
Q1: How does the energy regulation system on the SP6H3700 assist in system load matching?
A1: The three-stage capacity regulation (100%, 66%, 33%) enables operators to balance compressor displacement directly with cooling requirements, avoiding abrupt suction pressure drops and minimizing electrical spikes associated with full-power cycling.
Q2: What precautions should be taken regarding suction and exhaust pipe connections during installation?
A2: Installers must match line sizes with the designated 54 mm (2-1/8") suction and 35 mm (1-3/8") exhaust connections. The 360° rotatable stop valves allow flexible piping routing, but proper line support should be verified to avoid stresses on the valve bodies.
Q3: What routine checks ensure long-term stability of the internal motor and mechanical parts?
A3: Routine maintenance should include checking the oil level through the sight glass, monitoring suction gas superheat, and inspecting the outer suction filter screen during scheduled system overhauls to ensure no foreign debris bypasses into the cylinders.
Q4: What is the minimum order quantity and estimated production delivery time?
A4: We maintain 1 piece for in-stock sample orders. Standard production batch orders are typically fulfilled within 10 to 15 working days, while stock sample units can be prepared for dispatch in as fast as 3 days.
Q5: How are compressors packaged for overseas logistics?
A5: Compressors are packed in heavy-duty export wooden cases. Compressors shipped via sea freight include factory holding gas/refrigerant charges, whereas air freight shipments are cleared of pressure in accordance with international aviation safety regulations.
