Modular Electric Process Heating

The process heater,
rethought.

Thermocube is a standardized, modular electric heater for industrial process applications. Each 4×4×4 ft cube is a self-contained heating module — stack and connect them to match any heat duty from 200 kW to multi-MW.

How It Works

A heating platform, not a heater.

Thermocube replaces custom-engineered heaters with a standardized module. Inside each cube, alternating element and tube cassettes stand vertically side by side and slide out from the front face — all connections accessible from a single service plane.

200 kW

Per Module

Each 4 ft cube delivers up to 200 kW of process heat. Scale by adding modules — 3 cubes for 600 kW, a 2×2 stack for 800 kW, and larger arrays into the MW range.

Cassettes Per Cube

Five heating element cassettes and four process tube cassettes, stacked alternately. Each slides out independently for service without shutting down the system.

30 min

Reconfigure

Switch between parallel, series, or hybrid flow configurations by replumbing front-face VCR fittings. No internal changes to any cassette required.

Key Features

Built for industrial duty.

Modular Scalability

Any array geometry. Scale from a single 200 kW module to multi-MW installations by adding cubes — no redesign needed.

Front-Access Serviceability

All connections — electrical and process — on the front face. Isolate a single cassette, slide it out, and service without full shutdown.

Precision Control

Per-cube SCR power controllers with ±0.5°C accuracy. Fieldbus communication (Modbus/EtherNet IP) for granular zone control.

Predictive Monitoring

Integrated thermocouples and element resistance trending per cube. Know which module needs service before it fails.

Plug-and-Play Install

Ships pre-wired, pre-insulated, and factory-tested. No field construction. No combustion permitting. Commission in days.

Zero Combustion

100% electric. No fuel gas piping, no burner management, no Scope 1 emissions at the heater. ESG compliance built in.

Thermocube vs. Existing Heaters

How we compare.

Traditional process heaters are custom-engineered, site-built, and difficult to modify. Thermocube takes a different approach.

Frequently Asked Questions

Common questions.

What heat duty range does Thermocube cover?

A single module delivers up to 200 kW. Modules connect in any array configuration — 3 cubes for 600 kW, a 2×2 stack for 800 kW, and so on. The practical initial target range is 200 kW to 10 MW.

What fluids can it handle?

Process tubes are designed for thermal oils, glycol solutions, water/steam, and a range of chemical intermediates. VCR face-seal fittings are rated for 450°C+ service. Wetted materials are specified per application.

How is this different from a circulation heater?

A circulation heater is a single fixed unit — if an element fails, the entire heater must be taken offline for service. Thermocube's cassette architecture allows individual elements or tube bundles to be isolated and replaced while the rest of the system continues operating.

What electrical supply is required?

Standard 480V or 600V, 3-phase. Each cube has its own SCR power controller and connects to plant power via IEC 60309 industrial connectors on the front face.

Can I reconfigure the flow path after installation?

Yes. All process connections use VCR face-seal fittings on the front face. Switching between parallel, series, or hybrid flow configurations takes about 30 minutes of replumbing — no internal cassette changes needed.
