Drawing-Based Configuration
Heater type, duty, layout, mounting position, bracket or guard, and service access reviewed around the customer design.
East Thermal Tech
Custom Electric Heating Assemblies
Drawing-built heating packages for OEM cabinets, AHUs and data center support equipment. Anti-condensation, frost prevention and low-temperature protection.
- Heater + layout
- Bracket / guard
- Internal wiring
- Terminal handoff
3D concept, not a delivered project. Final assembly is project-specific.
Best Fit For
A practical fit for OEM teams that own the equipment or cabinet design and need a buildable heater subassembly around space, voltage, operating conditions, and downstream controls.
What We Provide
East Thermal Tech focuses on the heater subassembly inside customer-designed equipment. We work from drawings, internal photos, or a sample cabinet while the OEM retains the controller and final equipment integration.
Assembly-Ready Hardware
Heater, supports, internal leads, labels, and terminal handoff can be prepared as a coordinated package for prototype or repeat builds.
OEM Control Handoff
Wire route, terminal location, and thermostat or sensor position can be reserved for the customer's downstream controller.
Your Cabinet. Our Heating Assembly.
See how a heating assembly can fit into a customer-supplied cabinet: mounting brackets, heater, guard, routed leads, and defined terminal handoff points.
Assembly sequence and supply scope
- Customer cabinet: the enclosure and available space define the starting point for the heating layout.
- Mechanical assembly: brackets, heater, and ventilated guard are positioned around the customer design.
- Wiring route: internal leads follow a defined route with mechanical restraint and terminal reservation.
- Control handoff: heater connections and protective bonding are illustrated separately from the customer's downstream controls. This is not a construction wiring diagram.
- Prototype review: assembly layout, BOM outline, and wiring handoff notes support discussion before repeat production.
Send a cabinet drawing or internal photo with voltage, operating conditions, target temperature, and expected quantity. We supply heating assemblies, not complete control systems, liquid cooling systems, or MEP works.

Application Packages
Used where OEM equipment needs electric reheat, preheat, anti-condensation, frost prevention, or minimum-temperature support around a defined mechanical and electrical layout.
Custom AHU / HVACD Equipment
Project-specific preheat, reheat, freeze-protection, and control-enclosure heater assemblies.
Anti-Condensation
Heating packages to reduce condensation risk in enclosed electrical spaces.
Outdoor Low-Temperature
Cold-weather and frost-prevention support for exposed cabinet locations.
Data Center Power Cabinets
Heating assemblies for PDU, RPP, UPS, switchgear-related, and support cabinets.
Telecom / Edge Cabinets
Humidity, condensation, and low-temperature support for network and edge sites.
Generator Control Cabinets
Minimum temperature maintenance for standby power and outdoor control enclosures.
From Drawing to Repeat Build
Start with the available drawing and application. A sample cabinet shipment follows an agreed assembly proposal, not the first inquiry.
Project Intake
Cabinet drawings, photos, voltage, ambient temperature range, target internal temperature, and application background.
Heating Concept
Initial heater type, layout direction, mounting position, bracket or guard needs, and wiring route.
Assembly Proposal
Heating components, mounting approach, terminal reservation, and assembly notes for customer review.
Sample Cabinet
A sample build can be planned around your supplied cabinet, prototype enclosure, or cabinet mock-up.
Prototype Review
Feedback from installation, space, wiring, service access, and downstream control integration is reviewed.
Repeat Production
After confirmation, the heating assembly package can be prepared for repeat cabinet production.
Electric air heater product reference
Reference product only. The heater configuration is selected after project review.
Heating Assembly Architecture & Functions
The assembly is planned as a practical package of heater module, mechanical support, wiring route, and handoff point for the customer's downstream control system.
Heater moduleFinned tubular, tubular, or compact air-side heater selection based on space and duty.
Guard / bracketMounting support, protection guard, base, side-wall, or mounting plate arrangement.
Wiring routeWire length, exit direction, protection path, and service access reviewed around the cabinet layout.
Terminal reservationConnection point reserved for downstream controller, thermostat, or customer wiring handoff.
- Anti-condensation heating
- Low-temperature startup protection
- Temperature maintenance
- Frost prevention
- Heater mounting and installation support
- Wire routing and terminal reservation
- Heating layout based on cabinet drawings
- Prototype and repeat-production assembly planning
Typical Customization Range
Final heater rating, material, mounting method, wiring, labeling, and certification scope are confirmed per project after cabinet drawings and operating conditions are reviewed.
| Voltage | Project-specific; phase and frequency should be provided during RFQ review. |
|---|---|
| Heater wattage | Confirmed by cabinet volume, ambient temperature, target internal temperature, and mounting space. |
| Heater type | Finned tubular, tubular, or compact air-side heater depending on layout and service conditions. |
| Mounting | Bracket, guard, mounting plate, base, side wall, or other project-specific support. |
| Wiring | Wire length, exit direction, terminal reservation, labels, and wiring handoff notes. |
| Controls | Thermostat or sensor mounting position can be reserved for the customer's downstream controller. |
| Documentation | BOM, assembly photo, wiring handoff note, and inspection checklist can be prepared per order. |
Clear Project Handoff
A simple responsibility split helps engineering and sourcing teams evaluate the heater package without confusing it with the complete equipment or control scope.

Before Your First RFQ
The practical questions behind a custom heating assembly, before a sample or production order.
Can we start without a complete heater specification?
Yes. Share the application and the drawing or internal photo you have. Available space, supply voltage, ambient conditions and the required temperature are the next review inputs. Unknown items can be marked "to be confirmed".
Can you assemble the heating package in our cabinet?
Yes. A customer-supplied cabinet can be the basis for heating-system assembly. Mounting locations, incoming cabinet condition, delivery arrangements and the control handoff should be agreed before shipment.
How are heater wattage and protective measures decided?
Cabinet dimensions, heat loss, ventilation or airflow, ambient conditions, target temperature and available mounting space inform the review. A concept image is not a wattage calculation or a validated safety design. Protective measures and the customer's control interface must be defined for the exact assembly.
What are the minimum order quantity and lead time?
Both require project confirmation. Include the prototype quantity, expected repeat quantity and required date in your inquiry; the assembly scope and component availability need to be reviewed before a quotation or delivery commitment.
Does the assembly come with UL, CSA or CE approval?
Do not assume a certification applies to a custom assembly. Specify the destination market and required approvals before quotation. Heater-component documentation, assembly-level requirements and final equipment approval must be checked separately against the exact project and order.
Our drawings are confidential. How should we begin?
Begin with a non-confidential description or a redacted layout. Request an NDA before sharing proprietary drawings. The contracting entity, NDA terms and manufacturing arrangement must be confirmed before confidential documents or an order are exchanged.
Start Your Heating Review
Share the application and what the heater needs to achieve. Attach a non-confidential drawing or photo to your email; detailed specifications can follow.
Define the Deliverables Before the Build
A practical OEM handoff starts with the drawing and heater package, then the mounting and wiring details. Confirm the prototype before repeat production, with the required deliverables agreed in the order.
Product and concept images are reference examples. Final assembly, labeling, documentation, and certification scope are confirmed per project.
- Assembly BOM
- Mounting and bracket proposal
- Wiring handoff note
- Prototype assembly photos
- Inspection checklist per order
- Repeat-build configuration control
