High-Efficiency Valve System: Utilizes an optimized ring-type valve design for rapid response and excellent sealing, effectively reducing clearance volume and pressure loss, thereby establishing the foundation for high efficiency.
Robust Industrial-Grade Design: Incorporates a high-strength cast iron body, alloy steel crankshaft, and connecting rods, ensuring the compressor can withstand continuous high-pressure ratio operation and delivers a long service life.
Reliable Lubrication System: Features a positively offset crankshaft with splash lubrication, guaranteeing adequate lubrication for all critical moving parts. An optional crankcase heater is available to prevent refrigerant migration.
High-Performance Motor: Equipped with a built-in high-efficiency motor, cooled by direct suction gas flow for optimal cooling. The motor includes an inherent thermal protector to prevent overload damage.
Wide Refrigerant Compatibility: Designed for use with various common refrigerants including R404A, R507A, R134a, and R22, meeting the demands of different global markets.
II. Core Advantages
Outstanding Energy Efficiency Ratio (EER): Optimized internal design and the efficient valve system enable the DSH series to maintain excellent energy efficiency across full and part-load conditions, directly reducing electricity costs for users.
Unparalleled Reliability: "Industrial-Grade Durability" is its hallmark. Heavy-duty components and precision manufacturing ensure stable operation for tens of thousands of hours, even in the most demanding low-temperature freezing applications, minimizing downtime.
Precise Cooling Capacity Coverage: With five models from 090 to 161, the series offers a closely staggered, wide range of capacities. This allows system integrators to select the most precisely matched compressor for cold rooms or units of varying sizes, like fitting a puzzle piece, maximizing energy efficiency.
Low Maintenance Costs and Long Lifespan: The robust design and high-quality components translate to longer maintenance intervals and lower failure rates, significantly reducing the total cost of ownership over the equipment's lifecycle.
Global Brand and Service Support: Backed by the global network of Bier Refrigeration (carrying on the Danfoss legacy), users have access to timely technical support, genuine parts availability, and professional service.
III. Typical Applications The DSH compressor series is an ideal power source for the following areas, excelling particularly in medium- and low-temperature applications:
Commercial Refrigeration:
Large Supermarkets: Backroom compressor units for frozen food display cases, walk-in freezers.
Cold Chain Logistics: Low-temperature freezing warehouses (-25°C) in regional distribution centers.
