Product Introduction

QXD-S serieswater heaterIt is a heating equipment that uses water as the heating medium, stainless steel as the protective material for the electric heating element, and forced circulation through a hot water pump. It has the characteristics of small size, small footprint, energy efficiency, convenient use, cleanliness, and no pollution to the environment. It is an ideal small-scale heating equipment for industries such as rubber, molds, and pharmaceuticals.

Main features of QXD-S series electric hot water heater：

1. Small size, high power per unit volume of furnace body

The core component of the heater adopts bundled tubular heating elements, and the power of each bundled heating element can reach several KW or more

2. Fast thermal response, high thermal efficiency, and high temperature control accuracy

Due to the relatively small weight of tubular heating elements compared to other heating elements, the thermal inertia during start stop heating is small, and the heat converted by the heating element is quickly transferred to the medium, making temperature control very accurate

3. Beautiful appearance, compact structure, diverse combinations

The overall structure of the QXD-S series electric hot water heater is frame type, with the furnace body, pump, and accessories installed in the same frame. The heat exchanger and electronic control device can also be combined into one

4. Advanced design, reasonable structure, wide application range

The heating element is made of special materials, and to avoid excessive temperature of the wiring terminals, a non heating section with insulation sleeve structure is used; It can also be applied to explosion-proof and other occasions, and can adopt vertical or horizontal structure according to user needs

5. Intelligent control, automatic regulation, capable of implementing ontology/remote operation

The machine adopts PID intelligent instrument, which triggers solid-state relay through zero crossing to achieve stepless adjustment within the full power range, achieving precise temperature control and energy conservation; The heating system is also equipped with an automatic exhaust valve, a safety valve, and a pressure controller to automatically discharge gas from the system, stabilize the system pressure, and achieve dual protection functions of automatic water replenishment (if the water replenishment pressure is lower than the set pressure, heating will automatically stop to prevent dry burning) and overpressure automatic load relief and alarm; The machine can also be connected to the PLC in the DCS system and remote heating system to monitor the parameters in the remote PLC

6. Safe and environmentally friendly, high reliability, long service life

Due to the fact that electricity is a clean energy source, the power load of heating elements designed is mostly lower than the national standard, and multiple protections are adopted in mechanical and electrical control to improve their safety performance, thereby extending the service life of the equipment
