Shell & Tube Heat Exchangers

Heavy duty

Overview

Robust multi-tube thermal exchangers designed for high-pressure, high-temperature applications in boiler feed preheating, condensate recovery, and industrial process fluid heating.

  • Fixed tube sheet, U-tube, and floating head designs
  • Wide material selection for corrosive and fouling fluids
  • Customised for TEMA and ASME code compliance

Plate Heat Exchangers

High efficiency

Overview

Gasketed plate-and-frame exchangers that provide high heat transfer coefficients in a compact, expandable design—ideal for HVAC, district heating, and process fluid conditioning.

  • Easy plate pack expansion to increase capacity
  • Simple gasket replacement without special tooling
  • Counter-current flow for maximum thermal efficiency

Finned Coil Exchangers

Air-side heating

Overview

Extended surface finned tube coils for heating air streams in industrial driers, HVAC air handling units, and process heating enclosures using hot water or steam as the heating medium.

  • Aluminium, copper, and stainless fin options
  • Custom casing and duct connection flanges
  • Low airside pressure drop for energy-efficient fan operation

Brazed Plate Exchangers

Compact install

Overview

Copper or nickel brazed stainless steel plate exchangers offering maximum thermal performance in the smallest possible footprint—suited for domestic hot water, refrigeration, and secondary heating circuits.

  • No gaskets—hermetically sealed for leak-free operation
  • Handles high pressures up to 30 bar
  • Ideal for tight boiler room and plant room installations

Process Heating Systems

Direct heating systems that raise fluid or air temperatures reliably—from immersion heaters for tank heating to thermic fluid systems for high-temperature industrial processes.

Direct heating

Electric Immersion Heaters

Flanged, screwplug, and over-the-side electric immersion heaters for direct heating of water, oils, chemicals, and process fluids in tanks and vessels—from small batch heaters to multi-megawatt industrial units.

Hydromax immersion heaters are engineered with sheath material, watt density, and termination selected for your fluid, operating temperature, and environment—with thermostat and safety cut-out integration as standard.

Industrial Heating Applications

Purpose-engineered heating solutions for specific process requirements—from boiler feed preheating to pipeline frost protection across demanding industrial environments.

01

Process Water Heating

Centralised hot water generation systems for manufacturing processes, clean-in-place circuits, washdown stations, and industrial hygiene applications—maintaining precise temperatures across varying flow demands.

Hydromax process heating systems integrate storage vessels, circulation pumps, and temperature controls with heat exchangers or direct electric heating to match your production schedule and energy tariff.

02

Tank & Vessel Heating

External jacket, internal coil, and pad-type heating systems that maintain fluid viscosity, prevent solidification, or sustain reaction temperatures in storage tanks, process vessels, and buffer tanks.

We design tank heating systems for oils, chemicals, solvents, and treated water—selecting the heating medium and control strategy to minimise energy use while meeting process temperature hold requirements.

Pipeline Heat Tracing

Electric heat tracing and steam tracing systems that maintain pipeline temperatures to prevent freeze protection, viscosity control, and condensation along exposed or buried process lines.

Hydromax heat tracing packages include self-regulating cables, zone controllers, and thermal insulation specifications designed for reliable operation in outdoor, hazardous, and classified area installations.

Boiler Feed Water Heating

Economisers and feed water preheaters that recover heat from boiler flue gases or condensate return streams to raise feedwater temperature—reducing fuel consumption and improving overall boiler efficiency.

Our boiler feed preheating systems are designed to achieve a measurable reduction in fuel usage, with corrosion-resistant tube materials and bypass arrangements for flexible operation during load changes.

Temperature Control & Efficiency

Control systems, energy recovery, and monitoring solutions that keep heating plant running efficiently and process temperatures within specification around the clock.

Thermostatic temperature controls

Thermostatic Controls

PID-based temperature controllers, thermostats, and control panels that maintain process setpoints with precision—integrating with sensors, actuated valves, and plant SCADA systems.

Heat recovery systems

Heat Recovery Systems

Recuperators and heat recovery units that capture waste heat from exhaust streams, compressors, or hot effluent for reuse in process heating—reducing energy costs and carbon footprint.

Energy monitoring

Energy Monitoring

Heat metering, energy data loggers, and analytics dashboards that track thermal consumption per process, identify inefficiencies, and support ISO 50001 energy management compliance.
