Product Definition
Compact heat exchangers for building heating are high-efficiency heat transfer devices specifically developed for HVAC systems. They feature compact structural designs such as plate and spiral wound tube types, and utilize corrosion-resistant materials such as 304/316L stainless steel and titanium alloy as their core components.By optimizing the flow channel layout and the contact method of the heat transfer medium, it achieves efficient heat exchange between the heat source (municipal heating, heat pump, industrial waste heat, etc.) and the building heating terminal in a limited space. It is the core energy conversion component in centralized heating and individual heating systems.Its innovative design not only solves the problem of large space occupation of traditional heat exchangers, but also precisely matches the core needs of energy conservation and consumption reduction in modern buildings.
Product Features
High-efficiency heat transfer performance
The heat transfer coefficient reaches 4000-8000W/(m²・K), which is 30%-50% higher than that of traditional shell and tube heat exchangers. The heat transfer efficiency is further improved by 15%-20% through counter-flow arrangement design, and the comprehensive energy efficiency ratio during the heating season is ≥95%.Even under low-temperature heat source conditions, it can maintain stable heat exchange efficiency, ensuring that the heating system can quickly respond to heat load demands.
01
Compact space design
The heat transfer per unit volume reaches up to 170m²/m³, and the floor space occupied is only 30%-50% of that of traditional equipment. The modular structure is suitable for installation scenarios such as small equipment rooms and pipe wells, and the weight is reduced by more than 25%.The modular design allows for flexible expansion based on the building's heating area, eliminating the need for extensive additional installation space and significantly reducing the difficulty of construction and renovation.
02
Strong environmental adaptability
Temperature range covers -35℃ to 130℃, pressure rating is 0.6-4.0MPa, titanium alloy or titanium ceramic coating material can withstand high salt and high corrosive media, no risk of freezing and cracking in extremely cold environments of -35℃, suitable for different climate regions in the north and south.Special material treatment technology enables it to maintain a long service life even in acidic and alkaline media and environments with frequent temperature fluctuations, reducing equipment replacement costs.
03
Energy saving and low consumption advantages
Optimized flow channel design reduces system pressure to 0.05-0.2MPa. Combined with variable frequency control technology, it can reduce circulating pump energy consumption by 30%-50%, and the heat recovery rate is ≥90%, effectively reducing energy waste.The synergy between low voltage drop design and variable frequency systems can prevent energy waste and help buildings meet green building energy efficiency standards.
04
Convenient operation and maintenance features
The plate structure supports quick disassembly and cleaning, and the shell-and-tube end cap design facilitates scale cleaning. Some models are equipped with a digital twin early warning system to predict corrosion and scale risks in advance, extending the maintenance cycle by more than 30%.The digital twin early warning system can push device status information in real time via mobile phone. With standardized disassembly and cleaning procedures, even non-professionals can complete basic maintenance operations.

Product Functions
Core heat exchange function
accurately realizes the energy transfer of cold and hot media, efficiently converts the heat source temperature into the heating water temperature, adapts to the heating water temperature requirements of 0℃-95℃, and meets the heat load supply of different buildings (single unit heat exchange capacity covers 20kW-50000kW).It supports multi-media compatibility (such as hot water, steam, ethylene glycol solution, etc.) to meet the media adaptation requirements of different heating systems.
Stable operation guarantee
Integrated PID intelligent temperature control module, water supply temperature control accuracy ±0.3℃, supports 7×24-hour time-sharing temperature control, and maintains stable system pressure (fluctuation ±0.02MPa) through dual-pump redundancy design and pressure compensation device, avoiding vertical misalignment problem;The pressure compensation device can automatically balance the pressure in each branch of the system, effectively solving common problems such as vertical imbalance and insufficient heating at the terminal units in high-rise residential buildings.
System compatibility features
compatible with multiple heat sources such as centralized heating, ground source heat pumps, and gas boilers; can be matched with terminal equipment such as underfloor heating, radiators, and fan coil units; supports flow rate adjustment from 30% to 120%; adaptable to day and night load fluctuations.The flow rate adjustment range can be dynamically adapted according to the building's usage scenario (such as office hours and off-peak hours at night), taking into account both heating comfort and energy economy.
Energy-saving optimization function
Supports climate compensation control, dynamically adjusts output power according to outdoor temperature and humidity, and integrates a waste heat recovery module to recover heat energy in exhaust air to preheat fresh air, with a comprehensive energy saving rate of 10%-25%;The integrated design of the waste heat recovery module and the fresh air system can improve indoor heating efficiency while improving air quality, achieving multiple benefits at once.
Scope of Application
Residential buildings: centralized heating or individual heating projects for commercial housing, villas, and affordable housing;It is particularly suitable for scenarios such as narrow pipe shafts in high-rise residential buildings and the upgrading and renovation of heating systems in old communities, without the need for large-scale modifications to the original pipelines.
Commercial buildings: Hotels, office buildings, shopping malls, guesthouses, and other places that require a stable supply of heating and hot water;It can meet the characteristics of commercial venues with high traffic and large fluctuations in heating demand, ensuring uniform and stable temperature in different areas and improving user experience.
Public buildings: Schools, hospitals, stadiums, nursing homes, and other settings where high temperature accuracy is required;Designed to meet the temperature control needs of special locations such as hospitals and nursing homes, it enables precise temperature control and rapid fault response, ensuring the safety of use by vulnerable groups.
Industrial buildings: workshops, office buildings, and centralized heating systems in industrial parks, especially suitable for the renovation of old factories with limited space;It adapts to the linkage needs of waste heat recovery and building heating in industrial production processes, which not only reduces industrial energy consumption, but also provides a stable heat source for factories and office buildings.
