◎ Uses high-temperature hot water above 70℃ as the medium, using a carbon steel tube wound aluminum fin heat exchanger; ◎ The heat exchanger tube wall is thick and the tube diameter is large, with low water quality requirements, corrosion resistance, fouling resistance and freeze cracking resistance; ◎ Water pipes can enter and exit on the same side or both sides, bottom inlet and top return, threaded connection, optional flange; ◎ Available in standard and economical types. The economical type is suitable for places with low requirements for machine appearance. Standard type: The heat exchanger is built into the shell, and the shell is made of carbon steel plate electrostatic spraying white; Economical type: The heat exchanger is exposed, with visible welds, and the whole machine is sprayed with gray paint, with slightly lower aesthetics.
◎ Using steam with a pressure of 0.4 MPa or less as the medium, a carbon steel tube with aluminum finned heat exchanger is used; ◎ The pipe wall is thick, has good corrosion resistance, and high-pressure custom steel tube with steel finned heat exchangers are available; ◎ Water pipes are installed vertically or horizontally, with top inlet and bottom outlet, equipped with flanges, and a drain valve is required for return water; ◎ It is recommended to use pressure below 0.2 MPa to reduce the impact of high temperature of the heat exchanger on the motor; ◎ When using pressure exceeding 0.2 MPa, a solenoid valve must be installed, and the valve must be closed when the fan stops; ◎ If no solenoid valve is installed, local high temperature around the heat exchanger may trigger motor thermal protection or damage; ◎ Available in standard and economical types. The economical type is suitable for places with low requirements for machine appearance. Standard type: The heat exchanger is built into the shell, and the shell is made of carbon steel plate with electrostatic white spraying; Economical type: The heat exchanger is exposed, with visible welds, and the whole machine is sprayed with gray paint, with slightly lower aesthetics.
◎ Uses 60℃ low-temperature hot water and a copper tube-aluminum foil heat exchanger, requiring high water quality; ◎ Copper tube heat exchangers have high efficiency, but the thin tube walls and small diameter result in poor corrosion and scaling resistance; ◎ Water treatment equipment and temperature control are required to slow down scaling and corrosion of the heat exchanger; ◎ Continuous water supply is required in winter to prevent freezing. Water pipes have same-side inlet and outlet, bottom inlet and top return, with threaded connections.
◎ Uses 60°C low‑temperature hot water to produce 7°C chilled water, with the supply and return pipes on the same side—bottom inlet, top outlet. ◎ Employs a copper‑tube, aluminum‑fin heat exchanger; requires high‑quality water and must be equipped with water‑treatment equipment. ◎ The inlet and outlet pipes are connected via threaded joints; during summer cooling, condensate will form and must be drained through a dedicated pipe.
