Q: What is an inline heater?
An inline heater is an electric heating unit specifically designed to heat liquids as they flow through a pipe or system. It offers instant and controlled heating without the need for a storage tank. Inline heaters are ideal for applications that require consistent temperatures and compact installations, such as in process equipment, laboratories or small-scale industrial systems.
Q: What are the benefits of using an inline heater?
A: Inline heaters provide several benefits, including quick heat transfer, energy efficiency and accurate temperature control. They help maintain stable temperatures in liquids while minimising heat loss. As a result, inline heaters are a reliable and cost-effective alternative to large water heating systems.
Q: What liquids can an inline heater be used with?
A: Our inline heaters are designed for use with hot water and various non-corrosive liquids. They can be employed in both direct and indirect systems, depending on your specific needs. For aggressive or corrosive fluids, we recommend consulting our team to select the appropriate materials and heater configuration.
Q: What industries use industrial flow heaters?
A: Industrial flow heaters are utilised in various sectors, including manufacturing, food and beverage, pharmaceuticals, HVAC (heating, ventilation and air conditioning) and water treatment. They are especially beneficial for processes that require controlled heating for fluid circulation, cleaning systems and maintaining temperature.
Q: Do you offer customised inline heater solutions?
A: Yes, each inline heater can be customised to meet specific temperature, flow rate and material requirements. Our experts can design tailored industrial flow heaters with custom wattage, voltage and control options to fit your process or system layout.
