2000V PTFE Hot Water / Steam PTFE Coated Heating Elements

PTFE heater/PTFE heater

PTFE heaters use etched-foil elements sandwiched between rugged layers of PTFE. It can stand up to environments that would make damage in conventional metal-clad heating elements.

It is usually used in applications such as acid baths, medical devices and commercial appliances, etc.

Features and Benefits

non-sticky, heat resistant, wear and corrosion resistant, and easy to clean

Available in round, rectangular, or irregular shapes according to requirements

Provide stable heating performance below 250℃.

PTFE heater
PTFE heater consists of heating element and two layers of Teflon cloth. The Teflon cloth includes a glass fiber substrate layer, a Teflon coating and a silicone rubber layer.
The heater is very popular in the industry and has the advantages of not easy to wear, good insulation, easy to clean, safe and reliable, etc.

Features
1. The heater has excellent acid and corrosion resistance, and is not easy to produce chemical reactions.
2. Continuous working temperature can reach 250 ℃.
3. Resistant to atmospheric aging and radiation, as well as low permeability
4. Low dielectric loss, high breakdown voltage and long working life
5. Customized products avaliable for different needs

Specifications

The structure of PTFE steam heater and PTFE hot water heater has two types: shell and tube heater and tube bundle heater. The main part of them is a tube bundle consisting of many small-diameter thin-walled PTFE heat transfer hoses (see figure below). There are a variety of commonly used pipe specifications, outer diameter × wall thickness are 3 ~ 6mm × 0.3 ~ 0.6mm. The tube bundle contains 60-5000 tubes, and the two ends are separated from each other by PTFE tape. The tube bundle is inserted in a ring and welded into an integral honeycomb tube sheet. The other parts of the PTFE heater are similar to the common shell and tube heaters and immersion heaters that use metal tubes as heat transfer components.
 

The connection strength between the PTFE heater tube bundle and the tube sheet reaches 1.5Mpa. Through combination, it can be made into a variety of PTFE heaters. It is an ideal choice for strong corrosive, strong acid, and strong oxidizing medium heat transfer. Loved by the majority of users.
 

The working pressure, working temperature, heat transfer coefficient and installation method of PTFE heaters vary greatly according to different types, different shell materials and different heat media.
 

PTFE's chemical properties are extremely stable, and its corrosion resistance is particularly good. The surface of the PTFE tube wall is smooth and moderately flexible, and it vibrates slightly when used, so it is not easy to scale. The PTFE heater is small in size and compact in structure. The heat transfer area per unit volume of the equipment is more than 4 times that of the shell and tube heater of the metal tube.
