Customer Background
Recently, ELEKHEAT completed the production and shipment of a batch of customized copper screw plug immersion heaters for a customer in Germany.
The customer is an industrial equipment manufacturer who was looking for a reliable heating element supplier to replace their existing immersion heaters used in liquid heating equipment.
They contacted ELEKHEAT through our website and initially provided basic product information, including installation requirements, heater dimensions, and photos of their existing heating components.
Understanding the Customer's Requirements
During the communication process, the customer mainly focused on three key requirements:
- The new heaters needed to fit the existing installation structure
- The heating performance needed to remain stable during continuous operation
- The supplier needed to provide consistent quality for future orders
After reviewing the customer's requirements, ELEKHEAT's engineering team confirmed the heater structure and recommended a copper tubular heating solution with a threaded brass plug design.
The technical details were confirmed before production, including heater size, connection type, electrical specifications, and quantity.
