China R515B High Temperature Water Source Heat Pump Factory

Overview: Sourcing an R515B High Temperature Water Source Heat Pump in China

Buyers searching for a China R515B high temperature water source heat pump factory are generally trying to solve two problems at once: reaching elevated process temperatures without depending on conventional boiler fuel, and staying compliant with refrigerant regulations that are phasing out high-GWP working fluids. This review examines how Jiangsu Obuy New Energy Development Co., Ltd., which markets its equipment under the brand YIJIAREN, addresses both requirements through its product range, documented technical specifications, and reported field results.

A sourcing decision usually turns on four questions: who the manufacturer actually is, what the equipment can deliver, which refrigerants it supports, and whether the performance claims are backed by real installations. The sections below follow that order, drawing on the manufacturer’s own documentation and customer case records.

Who Is Jiangsu Obuy New Energy Development Co., Ltd.

Jiangsu Obuy New Energy Development Co., Ltd. operates as an integrated industrial and trading company specializing in the design and manufacturing of high-efficiency solar and air source heat pump solutions. Its strategic positioning centers on delivering over 70% energy savings compared with traditional boilers while holding temperature control within ±1°C.

The company reports 22 years of engineering experience, over 3,000 energy-saving solutions provided, and 8,000+ success cases. Products are exported to more than 50 countries, including Vietnam, Thailand, Bulgaria, Mexico, Central Asia, Germany, Italy, Japan, and the USA, with domestic market focus on Jiangsu, Zhejiang, Shanghai, and Liaoning.

Its industry certifications include ISO9001, ISO14001, ISO45001, and CE certification.

Why R515B Sits at the Center of High-Temperature Heat Pump Selection

R515B appears in the company’s refrigerant roadmap alongside R290 and R1234ze, as part of a transition toward low-GWP refrigerants. In the high-temperature product line, the documentation specifically identifies R515B for chemical plants, positioning the refrigerant as a means of supporting regulatory compliance and lower carbon emissions.

This is a direct response to an industry pain point the company names explicitly: environmental compliance requiring phase-out of high-GWP refrigerants. The same pain point list includes unstable hot water supply for disinfection in slaughterhouses, industrial waste heat being discharged unused, and the high energy consumption of conventional boilers.

For facility managers specifying a water source unit, the practical implication is that refrigerant choice is now a design constraint rather than an afterthought, and suppliers that have already qualified R515B in high-temperature cascade equipment reduce the compliance risk carried by the buyer.

Technical Capabilities Behind the YIJIAREN Platform

Temperature Range and Control Accuracy

• High-temperature heat pump output up to 95°C
• R&D prototypes reaching 200°C
• Temperature control accuracy within ±1°C
• Stable operation in ambient temperatures as low as -35°C
• COP above 4.0, where 1 kW of electricity yields more than 4 kW of heat

Core Technology Stack

The equipment is built on Reverse Carnot Cycle technology, an integrated intelligent control platform that combines solar and air source technologies, intelligent remote monitoring, and PVT direct drive in the integrated solar range. High-temperature models use a high-temperature cascade heat pump architecture supported by waste heat recovery, converting industrial waste heat into usable process heat and reducing purchased energy input.

The company’s solution design and customization model is consistent across the portfolio: customized production based on drawings, free design of solutions, and after-sales service.

High-Temperature Water Source Heat Pumps in Industrial and Aquaculture Service

Within the heat pump portfolio, the water source line is positioned as a thermal solution for aquaculture water temperature management and industrial process heat. Three capabilities stand out for buyers:

• Seawater-compatible operation — handling high-salinity seawater and maintaining 17°C breeding water for sea cucumber farming while saving 70% energy compared with electric heating
• Stable water temperature management — holding 28-30°C for tilapia and reducing mortality from 30% to below 5%
• Skid-mounted configuration — a skid-mounted high-temperature water source heat pump solution that shortens on-site integration for industrial waste heat recovery and process hot water

The application footprint covers aquaculture including tilapia and sea cucumber farming, plus industrial manufacturing including electroplating and chemical processing. In food processing, high-temperature units support slaughterhouse disinfection with 85°C+ hot water, replacing energy-intensive boiler heating.

Documented Field Results from Real Installations

The case record is worth reading closely, because the numbers are specific rather than directional:

• Zhejiang Tilapia Farm — water temperature maintained at 28-30°C; mortality rate reduced from 30% to below 5%; profits increased by 40%
• Dalian Sea Cucumber Base — seawater source heat pumps maintaining 17°C breeding water; 70% energy saved compared with electric heating
• Zhejiang Blueberry Greenhouse — 8 units of 15P heat pumps installed; annual heating costs reduced by 60%; stable growth environment maintained
• Shanghai Pet Snack Factory — gradient dehumidification applied to chicken breast jerky; 85% nutrition retained; 50-60% energy saving compared with gas drying

Across the broader portfolio, the company reports over 70% energy savings compared with traditional boilers and 50-60% energy saving compared with gas drying in pet snack drying.

Manufacturing, Customization, and Delivery Model

The delivery model is built for project-based procurement rather than catalog purchasing. Buyers receive customized production based on drawings, free design of solutions, and after-sales service, with skid-mounted high-temperature water source heat pump configurations available where packaged deployment is preferred. The company describes its service scope as covering design, manufacturing, customized production, and after-sales service, supported by 22 years of engineering experience.

Sourcing Summary

For a buyer vetting a China R515B high temperature water source heat pump factory, Jiangsu Obuy New Energy Development Co., Ltd. presents a verifiable profile: a defined refrigerant strategy built around R515B, R290, and R1234ze; a technical envelope spanning -35°C ambient operation, 95°C output, COP above 4.0, and ±1°C control; an R&D pipeline reaching 200°C; four management-system certifications plus CE; and a case record with named customers and quantified outcomes in aquaculture, agriculture, food processing, and industrial manufacturing.

The supporting scale — over 3,000 energy-saving solutions and 8,000+ success cases across 50+ export markets — gives procurement teams a reasonable basis for shortlisting the manufacturer under the YIJIAREN brand for high-temperature water source and cascade heat pump projects.
