The Circulation Heater is a closed-loop inline heating system that pumps fluid through a pressurized vessel containing high-density heating elements, delivering precise outlet temperature control for continuously circulating process fluids. Equipped with inlet/outlet thermocouples, PID controllers, and optional flow switches and low-level protection, it maintains tight temperature tolerance (±1°C) regardless of flow variations. Essential for thermal oil heating systems, glycol/water mixtures for climate control, chemical reaction preheating, and purified water loops in pharmaceutical manufacturing.

Typical Specifications: Power: 3kW–600kW; Vessel design pressure: up to 100 bar; Flow rate: 1–200 L/min; Temperature range: ambient to 400°C; Accuracy: ±0.5°C~±1°C; Vessel material: SS316/CS; Options: ASME U-stamp, NACE MR0175 compliance.
