Water is the most common medium in industry, and also one of the most temperature-sensitive in a hose. In cold surroundings an exposed water line can freeze and block, and even in a heated hall the water cools on its way from the heater to the consumer, so the temperature at the outlet is never quite what was set. The JINGCHENG Anti-Freeze Constant Temperature Heated Water Hose is part of our constant temperature hose range. It provides heat tracing and insulation along the whole line, keeping water and aqueous solutions at a controlled temperature and protecting them from freezing. The hose is heat resistant up to 100°C, higher temperatures are available on request, and every line can be customized to your requirements.
Freeze protection: heat tracing prevents the medium from freezing in the line when the surroundings are cold
Constant delivery temperature: the heating layer replaces heat lost through the wall, so water arrives at the set temperature
Length-independent performance: long lines keep the same temperature as short ones because heating runs the full length
Wide ambient range: the catalog operating environment covers ambient temperatures from -40°C to +55°C
The medium flows through an inner tube customized to the application. Tell us whether the line carries water or an aqueous solution, and at what temperature, and our engineers will confirm the build.
The heating layer is made of uniformly braided heating elements. They distribute heat evenly over the inner wall and minimize temperature differences along the line, so there are no unheated sections where water can cool or freeze.
High-insulation-efficiency materials surround the heating layer, selected with the outer surface temperature in mind. The insulation keeps heat inside the line, which lowers energy consumption, especially in cold surroundings.
A Type J or Type K thermocouple, Ni120, PT100 or PT1000 sensor can be integrated so a controller holds the line at a constant set point. Supply voltage can be 380 Vac, 220 Vac, 110 Vac, 12 Vdc or another value.

Each JINGCHENG electrically heated hose is assembled to the buyer's specification. The catalog order form covers the following items:
Parameter | Options listed in the catalog |
|---|---|
Supply voltage | 380 Vac, 220 Vac, 110 Vac, 12 Vdc or other |
Temperature sensor | Type J thermocouple, Type K thermocouple, Ni120, PT100, PT1000 or other |
Hose length | 3 m, 4.5 m, 5 m, 6 m, 10 m or other |
Inner diameter | Φ8, Φ12, Φ16, Φ19, Φ25 mm or other |
Working pressure | 4 MPa, 10 MPa, 20 MPa, 35 MPa or other |
Heating power | 110 W/m, 150 W/m, 170 W/m, 200 W/m or other |
End fittings | US, British or metric threads, or other |
Wiring | Pin number, wire color and function at the controller end and the gun/tool end |
A typical code such as JCH-200-16-B-3X220-P2-8 is read as follows: 200 = working temperature 200°C; 16 = inner diameter Φ16 mm; B = inner tube type (B stainless steel corrugated tube, TB PTFE hose with stainless steel braid, T PTFE hose, X special material); 3X220 = supply (220 = 220 V single phase, 3X220 = three-phase four-wire 220 V); P2 = sensor (P2 PT100 two-wire, P3 PT100 three-wire, K Type K, J Type J, W no sensor, T special sensor); 8 = working pressure 8 MPa.
Ambient temperature -40°C to +55°C, relative humidity not above 85%
Atmospheric pressure 86 kPa to 106 kPa; voltage range 12 Vac to 380 Vac
No gases that corrode metal or damage insulation, no conductive media and no severe mold in the surroundings; other environments are handled as custom builds
Connect the hose strictly according to its technical data and the pin table delivered with it.
Never twist the hose sideways during or after installation; torsion can lead to leakage, flow loss, hose damage or fire.
Keep bends generous; over-bending can damage the hose and cause short circuit, leakage or fire.
Let only authorized, trained operators handle the hose, ideally a dedicated team.
Unauthorized modification or adjustment voids the warranty.
For any situation not covered by the instructions, contact JINGCHENG engineers for installation guidance.
Send your inquiry by phone, fax or the website inquiry form.
Our engineers confirm the most suitable specification as the basis for quotation.
You receive a quotation and confirm with a purchase order.
The hose is produced in our factory to the confirmed specification.
Every hose is inspected for defects and packed.
The order is shipped to your designated address.
Medium and set point: water or the aqueous solution to be carried, and the constant temperature required (standard up to 100°C).
Ambient conditions: the lowest surrounding temperature the line will see, indoors or exposed.
Bore and length: an inner diameter from 1/4" to 1" for your flow, and the full route length.
Electrical data: supply voltage, power per meter and the controller's sensor type.
Connections: US, British or metric threads and the connector pin assignment.
Does the hose need a separate controller? The built-in sensor is read by a temperature controller; you can use your own or ask JINGCHENG about a matching controller.
Can the hose be made for temperatures above 100°C? Yes, higher temperatures are available on request after our engineers review the application.
Shenzhen Jingcheng High-Tech Co., Ltd. has manufactured PTFE hoses and electrically heated hoses since 2005. Send us your medium, set temperature, ambient conditions and line length for a matching water hose specification and quotation.
