I. Product Overview The MT/MTZ 160HW and MTM/MTZ200 HSS belong to a series of commercial semi-hermetic reciprocating compressors. Designed for high-capacity, continuous operation in demanding environments, they set the benchmark in the cold chain, supermarket, and industrial refrigeration sectors with their unparalleled durability, powerful cooling capacity, and wide applicability. These compressors serve as the ideal power core for critical systems in medium-to-large cold storage facilities, freezing processes, and cold chain logistics. The series offers various cylinder bore sizes and displacements to meet a broad spectrum of needs, from standard freezing to ultra-low-temperature applications. II. Core Features & Advantages1. Extreme Reliability & Long Service Life
Heavy-Duty Construction: Features a high-strength cast iron body, large bearings, and precision-machined crankshaft and connecting rod mechanisms, ensuring stable operation even under extreme conditions and a design life far exceeding that of standard commercial compressors.
Superior Cooling System: An efficient cylinder head and motor cooling design maintains normal operating temperatures even under high compression ratios and ambient temperatures, preventing overheating damage.
Robust Lubrication System: A high-capacity, high-pressure forced-feed oil pump ensures all moving parts are adequately lubricated, minimizing wear.
2. High-Efficiency Performance
Optimized Valve Design: High-efficiency suction and discharge valves and flow path design reduce pressure drop, increasing volumetric efficiency and Energy Efficiency Ratio (EER).
High-Performance Motor: Utilizes high-efficiency motors with a high power factor, ensuring smooth operation and significant energy savings.
3. Wide Applicability
Broad Operating Range: Capable of operating effectively from medium-temperature refrigeration (approx. -10°C) to low-temperature freezing (approx. -40°C).
Comprehensive Refrigerant Compatibility: Fully compatible with R404A and R507A, and also suitable for newer environmentally friendly refrigerants such as R448A, R449A, and R513A, facilitating a smooth transition to a low-carbon future.
4. Easy Maintenance
Semi-Hermetic Design: Allows for major field servicing, such as valve plate assembly, shaft seal, or bearing replacement, without welding, significantly reducing maintenance difficulty and downtime.
Standardized Connections: Designed for easy installation and service.
III. Model Differences & Selection Guide The primary distinctions within this series lie in construction, displacement, and cooling capacity:
MT/MTZ 160HW: Typically refers to a compressor with a displacement of approximately 160 m³/h, often in 6 or 8-cylinder configurations. Suitable for applications requiring high cooling capacity, such as large cold storage warehouses and freezing tunnels.
MTM/MTZ200 HSS: Typically refers to a compressor with a larger displacement of approximately 200 m³/h, often an 8-cylinder design. This is the higher-capacity model in the series, providing powerful performance for ultra-low-temperature freezing, quick freezing, and other extreme conditions.
Typical Applications
Large Cold Storage Warehouses: Refrigeration (-25°C) and freezing (-35°C to -40°C) warehouses in distribution centers and logistics hubs.
Food Processing: Spiral/tunnel freezers, plate freezers, and cooling systems for food processing areas.
Industrial Refrigeration: Chemical process cooling, low-temperature testing environments, ice rink and snow venue cooling systems.
Cold Chain Logistics: Refrigeration units for large container transport.
