3D concept of a guarded cabinet heater assembly with mounting plate and routed leads

East Thermal Tech / For AHU & precision-cooling OEMs

Heating Assemblies for AHU Electrical Cabinets

Cabinet anti-condensation and low-temperature heating, with mounting, guard and lead routing matched to your design. Your team retains the controls.

Discuss Your Cabinet ScopeView Catalog

3D concept, not a delivered project. Final assembly is project-specific.

Does your equipment have a cabinet heating requirement?

Start with the electrical enclosure, not the whole AHU. Tell us whether the concern is condensation, cold-weather standby or minimum internal temperature. We can discuss the supply boundary before you share drawings or plan a sample shipment.

Best Fit For

OEMs that own the complete equipment design and have an electrical enclosure heating requirement. These are potential applications for discussion, not customer references or confirmed equipment approvals.

Precision Cooling OEMs

Electrical cabinets associated with CRAH, CRAC and fan-wall equipment where a cabinet heating need has been identified.

Custom AHU Builders

Customer-designed electrical or service cabinets that require a heater package without transferring the control-system scope.

Outdoor Equipment OEMs

Cabinets exposed to low ambient temperatures or condensation risk during operation, standby or shutdown.

Four Cabinet Review Points

Review the enclosure, its operating conditions and the interface to the OEM controls before selecting a heater rating.

Condensation RiskHumidity, temperature changes, cabinet ventilation and standby conditions.
Low Ambient OperationMinimum ambient and target internal temperature, with cabinet heat loss to be assessed.
Mechanical FitMounting area, guard clearance, component separation and service access.
Control HandoffLead route, terminal location and reserved sensor or thermostat mounting position.

Main-air-stream preheat or reheat requires a separate capability review. This page does not offer a rated duct heater, complete air-treatment system or humidity-control guarantee. For low-dew-point, battery or semiconductor equipment, confirm the exact cabinet requirement first.

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.

Review the Sample Cabinet Before Repeat Production

A heater can fit the mounting space yet obstruct a terminal or service route. We review the proposed heating assembly around your cabinet drawing, then use prototype feedback to agree changes before a repeat configuration is approved.

45-second concept animation: an initial retainer obstructs a proposed terminal access path; a revised part is reviewed against the same space. Illustrative geometry only, not a customer installation, verified clearance, wiring instruction, or performance test.
  1. 1. Agree the InputsCabinet drawing and revision, supply voltage, temperature conditions, mounting space, and an agreed customer-supplied sample cabinet where required.
  2. 2. Review Fit and HandoffHeater mounting, guard retention, lead routing, reserved terminals, and access for the customer's downstream control integration.
  3. 3. Confirm the Repeat BuildResolve review comments and agree the assembly revision, BOM, photos, wiring handoff note, and inspection scope per order.

Heating assembly only. Downstream controls remain with the OEM. Final rating, protection, mounting, testing, and certification scope must be confirmed for the exact project; this concept does not establish those requirements.

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.

Inputs for Engineering Review

After an initial scope discussion, share the available information below. Unknowns can be listed for review; a cabinet shipment is only planned after agreement.

Cabinet Layout

  • Approved drawing or internal photo
  • Available mounting space
  • Ventilation and service access

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

Start with the Cabinet Requirement

We will first discuss whether the requirement fits our heater-assembly scope, then identify the technical inputs needed for a proposal.
