High Temperature Air Source Heat Pump

85°C Max Water Temperature: Direct drop-in replacement for gas/oil boilers in existing high-temperature radiator networks and industrial thermal loops.

Full Heating Capacity Down to -20°C: Enhanced Vapor Injection (EVI) scroll compressor maintains refrigerant mass flow in sub-zero ambients, eliminating severe capacity drop-offs.

Economizer Plate Heat Exchanger: Dual-stage subcooling circuit boosts overall Coefficient of Performance (COP) by up to 18% in low ambient conditions.

Low-GWP Refrigerant Options: Factory configurations available for R134a, R410A, and natural refrigerant R290, complying with F-gas regulations.

Modular Scalability: Parallel connection support up to 16 units, delivering a centralized heating capacity of up to 2.4 MW.

EVI Compression Mechanics
Intermediate-pressure refrigerant vapor is injected into the compression chamber mid-cycle, controlling discharge temperature and boosting mass flow at low suction pressures. This prevents motor thermal overload and sustains 80°C water output at -15°C outdoor ambient.

Dynamic Defrost Logic
Thermal imaging sensors and real-time pressure transducers monitor evaporator coil surface enthalpy. Reverse-cycle defrost initiates only when required, minimizing thermal inertia loss in the buffer tank.

Core Bill of Materials (BOM)
Expansion Valves: Electronic Expansion Valves (EEV) with 500-step resolution.
Heat Exchangers: Shell-and-tube or brazed AISI 316 stainless steel plate heat exchangers rated to 4.5 MPa working pressure.
Controller: Industrial PLC (Siemens / Carel) with Modbus RTU/TCP protocols for BMS integration. 

Industrial Processes: 75°C to 85°C water loops for textile dyeing, industrial washing, chemical reactor pre-heating, and food pasteurization.

District Heating: Multi-story residential and municipal retrofits utilizing existing cast-iron radiator networks (70°C supply requirement).

Agricultural Dehydration: Constant-temperature greenhouse heating and commercial product drying kilns.

Hybrid Boiler Integration: Baseload heat source positioned downstream/upstream of gas boilers, cutting annual natural gas consumption by 65% to 75%.

Hydraulic Layout: Custom port positioning, variable-speed circulation pumps, and internal expansion vessel sizing per project schematics.

Structural Engineering: Galvanized steel frames with C4 powder coating or full marine-grade 304/316 stainless steel enclosures.

Electrical Protocols: Voltage tailoring (220V–480V, 50Hz/60Hz) and UL/CSA compliant panel layouts.

Software & Branding: Custom HMI touch-panel firmware, multi-language UI, and private-label badging.

Helium Leak Detection: 100% pressure-vessel and circuit helium mass spectrometry testing (leak rate < 1 x 10^-7 Pa·m^3/s).

Run-Test Chambers: Fully automated psychrometric testing simulating -30°C to +50°C environments to verify capacity and COP under load prior to dispatch.

Electrical Verification: 2000V high-voltage dielectric withstand testing and earth continuity checks on every unit.

Certifications: ISO 9001:2015 facilities. Compliance with CE (Machinery Directive, PED 2014/68/EU), ErP Directive (Efficiency Class A++ / A+++), and RoHS.

Crating: Fumigation-free plywood crating with internal elastomer compressor shock mounts. Moisture-barrier vacuum-sealed foil bagging with silica gel desiccants.

Handling: Base frame integrated with forklift slots and certified crane lifting lugs.

Logistics: Standardized 20'GP/40'HQ container loading equipped with tilt-watch and shock-watch indicators.
