For mission-critical air-side equipment OEMs

Custom HVACD & AHU Heating Assemblies

Electric preheat, reheat, freeze-protection, and control-enclosure heater subassemblies configured around your equipment drawing, mounting space, voltage, and downstream control plan.

Concept illustration. Final assembly is project-specific.

Best Fit For

OEMs that already own the complete equipment design and need a defined heating package that can be mounted, wired internally, reviewed in a prototype, and handed off to the customer's controller.

Precision Cooling

CRAH, CRAC, fan-wall, and related mission-critical air-side equipment.

Custom Air Handling

Project-built AHUs requiring preheat, reheat, or cold-weather heater sections.

Special Environments

Outdoor HVACD modules, low-dew-point equipment, battery or semiconductor environmental systems.

Where Electric Heating May Fit

The exact location and duty are confirmed by the OEM. These are common review points, not a complete HVACD system design.

What We Configure

Heater & Mechanical Package

Heater type and layout, frame or mounting plate, brackets, guard, clearance, and service access.

Internal Wiring Handoff

Lead length, exit direction, labels, wiring route, terminal reservation, and sensor or thermostat mounting position.

Prototype Documentation

Assembly BOM, assembly photos, wiring handoff note, and inspection checklist can be prepared per order.

Responsibility Split

East Thermal Tech supplies the heater subassembly scope. The OEM retains the equipment design, controls, protection, final validation, and certification decisions.

East Thermal Tech

  • Heater package review
  • Mounting and guard arrangement
  • Internal leads and labels
  • Terminal handoff reservation
  • Prototype and repeat-build assembly planning

Customer / OEM

  • Airflow and complete HVACD design
  • Controller, sensors, alarms, and operating sequence
  • Final protection and system integration
  • Finished-equipment testing and approval
  • Certification requirements for the final unit

We are not offering liquid cooling, a complete HVACD system, full MEP work, or a complete control system. Certification scope is confirmed per exact custom assembly and order.

What to Send

Begin with the information already available. One equipment section drawing or internal photo is usually the most useful starting point.

Equipment Layout

  • Drawing, section, or internal photo
  • Available mounting space
  • Airflow direction if applicable

Operating Conditions

  • Voltage, phase, and frequency
  • Ambient temperature range
  • Target temperature or heating purpose

Project Handoff

  • Controller or thermostat plan
  • Lead and terminal preferences
  • Prototype quantity and destination market
