Product Overview

Heat exchangers are core components in heating, ventilation, and air conditioning systems - transferring thermal energy between fluids to enable heating, cooling, and heat recovery. Our comprehensive heat exchanger product line includes both plate heat exchangers and shell & tube heat exchangers, with configurations ranging from standalone units to fully integrated heat exchanger skids. All products are engineered for high efficiency, durability, and ease of maintenance, suitable for district heating/cooling, domestic hot water, process cooling, and other HVAC applications.

Plate Heat Exchanger

Working Principle

The plate heat exchanger consists of many corrugated heat transfer plates pressed together with rubber gaskets at intervals. The plates are corrugated to increase surface area and rigidity, and to create turbulent flow at low velocities for enhanced heat transfer. Two heat exchange media flow through separate channels in counter-current flow through each plate for efficient heat exchange. The design allows easy disassembly without removing piping.

Key Features

High Efficiency

Heat transfer efficiency is over 5 times that of shell-and-tube heat exchangers.

Compact & Lightweight

Plate thickness only 0.4–0.8mm, weight approximately 1/5 of shell-and-tube equivalents.

Small Temperature Difference

Can operate effectively with a minimum temperature difference ≤ 1°C.

Easy Maintenance

1–2 persons can disassemble and reassemble a large unit.

Anti-Vibration Design

Prevents loosening of bolts and leakage during operation.

Material Options

Stainless steel (304, 316, 316L), titanium, Hastelloy, and more for various fluid compatibility.

Gasket Options

NBR, EPDM, FKM, Neoprene, Silicone for temperatures from -65°C to 220°C.

Shell & Tube Heat Exchanger

Working Principle

The shell & tube heat exchanger consists of a shell, tube bundle, and tube sheets. One fluid flows through the tubes (tube side) while the other flows around them (shell side). Heat is transferred through the tube walls between the two fluids. Suitable for high-temperature and high-pressure applications, including steam-water heat exchange.

Key Features

High Temperature & Pressure Resistance

Suitable for high-temperature, high-pressure steam applications.

Durable Construction

Long service life with robust materials.

Versatile Applications

Suitable for steam-water and water-water heat exchange.

Compact & Lightweight

Compared to traditional designs.
