FAQ

Q: Are electric immersion heaters safe?

A: Is it safe to use an immersion heater?

Yes, it is, provided you buy a good product and use it appropriately.

You can even use it to boil drinking water and coffee.

Electrocution, burns, and short circuits may occur if you do not use the correct immersion water heater or wrongly utilize it.

Q: Where is Surplus located?
A: Our office located in HongKong,Dongguan and Shantou City.Our factory located in Shenzhen.

Q: Can I buy direct?
A: Yes,you can buy from Surplus Directly.

Q: Do you manufacture your products in house?
A: Most of our products are manufactured in-house at our factory.Some accessory items are not.

Q: Can I get the riser on my L-shaped aquaculture heater longer/shorter?
A: Yes.There is no price difference for making a heater with a middle riser,but there maybe a cost adder for a longer riser.

Q: What Third Party Approvals do your products carry(CE?)
A: Almost all of our products are CE compliant.

Q: How late can you ship?
A: Normally 7 days after comfirmed the order.

What Are The Industrial Applications Of Inline Heaters?

Inline heaters, sometimes referred to as circulation heaters, have a number of different industrial uses.

Inline heaters make use of heating elements that are covered with a special type of vessel chamber that has anti-corrosion properties. This type of heating is indirect. The fluid is circulated through a closed loop around the heating element until it reaches the correct temperature. Then it’s passed out of the tank through a nozzle. Different uses may require different flanged connections, sheath materials, or temperature ranges. These heaters are often insulated to help increase their efficiency.

An inline chemical heater is a device that heats a fluid as it flows through a pipe or tube, rather than heating a whole tank of liquid. These heaters are designed to quickly heat the fluid at the point of use, offering advantages like faster heating, reduced heat loss, and improved efficiency. They are commonly used in industrial settings for heating chemicals, solvents, and other fluids in processes like semiconductor manufacturing, chemical processing, and fluid handling.

Key Features and Benefits of Inline Chemical Heaters:

Fast Heat-up:
Inline heaters allow for rapid heating of continuous fluid flows, eliminating the need to wait for an entire tank to reach the desired temperature before using the heated fluid.

Point-of-Use Heating:
The fluid is heated directly where it's needed, minimizing heat loss and energy consumption.

Efficient Energy Usage:
Focusing heat on the flowing fluid reduces energy waste compared to heating a large volume.

Versatile Applications:
Inline heaters are available in various designs and materials to handle a wide range of chemicals, solvents, and temperatures.

Material Compatibility:
Many inline heaters are made with materials like stainless steel, fluoropolymers (PFA/PTFE), quartz, and titanium to resist corrosion and chemical reactions.

Safety Features:
Some inline heaters incorporate features like gas purging to remove chemical permeation, temperature sensors, and self-limiting technology for safe operation in various conditions.

Customization:
Options for single-pass or recirculating applications, different power outputs, and various fluid connections enable customization for specific process needs.

Low Wattage Options:
Some inline heaters are designed for low wattage, making them suitable for sensitive chemistries and applications where maintaining precise temperature control is crucial.

Applications of Inline Chemical Heaters:
Semiconductor Manufacturing:
Heating chemicals for cleaning wafers, stripping resist, and various process steps.

Chemical Processing:
Heating and maintaining temperatures for chemical reactions, mixing, and other process steps.

Solvent Handling:
Heating solvents for use in cleaning, extraction, and other applications.

Ultra-High Purity (UHP) Applications:
Inline heaters designed for ultra-high purity materials are essential for processes like deionized water heating, pharmaceutical manufacturing, and advanced materials science.

Types of Inline Chemical Heaters:

• TIH (Titanium Inline Heater): Designed for durability and safety, often used for heating acids and ultrapure DI water.
• Lufran Chemical Heater: Offers safe heating of a variety of chemicals with stainless steel wetted surfaces.
• Frontier Inline Heater: Designed for hazardous environments, suitable for flammable and non-flammable chemistries.
• SHB/SHC Inline Heaters: Low wattage heaters for indirect heating of chemicals and solvents.
• Inline Heater: Compact heating solution for non-flammable chemistries in single-pass or recirculating applications.
• Quartz Inline Heaters: Utilize quartz tubes for heating ultrapure fluids.
• SHX Inline Heater: For heating IPA and other solvents, meeting stringent cleanliness requirements.
