Thermal Products Heating Systems

Industrial Air Services' Thermal Products offering covers industrial heat transfer and process equipment, including heat exchangers, heating equipment, cooling solutions, and related system components.

A heat exchanger transfers thermal energy between fluids, typically through a separating surface. Selection balances required heat transfer, pressure drop, material compatibility, and cleaning needs.

Shell-and-tube units route fluid through tubes and a surrounding shell. Plate units use channels between plates, offering different layouts, service access, and operating limits.

Process heating raises or maintains a material's temperature for production. Applications require matching heater type, heat input, control method, and fluid-contact materials to the process.

An immersion heater transfers heat through an element positioned in a suitable fluid. Material compatibility, allowable surface loading, liquid level, and temperature controls are important selection factors.

A thermal-fluid system circulates a heat-transfer medium between a heater and process equipment. Fluid selection, operating temperature, expansion, circulation, and monitoring must be considered together.

Air-cooled equipment rejects heat to surrounding air, while water-cooled equipment transfers heat to a water circuit. Available utilities and required temperatures influence the suitable arrangement.

Provide both fluids, flow rates, inlet and outlet temperatures, operating pressures, allowable pressure drops, and fouling information. Include material requirements and available space.

The temperature difference between the two streams near an exchanger's limiting point affects required surface area. A close temperature approach can demand a larger or different exchanger design.

Deposits add thermal resistance and may restrict flow. Equipment selection and maintenance should account for likely buildup and how the exchanger can be cleaned effectively.

A suitable construction may be available after reviewing chemistry, concentration, temperature, and pressure. Compatibility must include plates or tubes, gaskets, seals, and all other wetted parts.

Appropriate upstream filtration or straining can limit debris entering narrow passages. It does not remove every contaminant or replace the need to manage scaling and fluid chemistry.

Recovery may be practical when a heat source and useful heat demand are available at compatible temperatures. Evaluate operating schedules, exchanger requirements, and potential contamination barriers.

Inspect heat-transfer surfaces, seals, supports, sensors, and controls as applicable. Track temperatures and pressure drop so loss of performance can be distinguished from changing process conditions.

A replacement requires review of duty, ratings, materials, dimensions, and controls. Updated process data may reveal that a direct copy of the original equipment is unsuitable.
