Custom Furnace Design That Starts With Your Requirements
A custom build with us isn’t a standard unit with a bigger door. We modify size, chamber design, heating configuration, atmosphere, and features to match how you run. Need a specific hot zone length, a controlled inert atmosphere, a rotary tube for powder and granular material, or vacuum capability down to a target Torr level? We design around it.
The temperature ceiling is rarely the constraint. Our engineers work on muffle, tube, and vacuum platforms:
- Muffle Furnaces: rated up to 1800°C (3270°F)
- Tube Furnaces: rated up to 1700°C (3090°F)
- Vacuum Furnaces: rated up to 1600°C (2910°F)
Precise temperature control is where a custom furnace earns its keep. Every unit ships with a 30-segment programmable PID controller that lets you set heating rates, dwell times, and cooling rates for repeatable results run after run. When your application demands tight uniformity, we can hold the chamber to roughly +/-5°C and add an air circulation fan to reach +/-2°C, where necessary.
Built To Solve the Problems Procurement Worries About
Energy cost per cycle is a line item you feel. Our furnaces use ceramic fiber board lining and a double-shell design that keeps heat in the chamber and the outer shell cool, reducing energy waste and protecting people working near them. Safety is engineered in, not bolted on. A door interlock cuts power the moment the furnace opens, and an optional independent thermocouple with an over-temperature controller shuts down the elements before a runaway costs you a batch or a repair.
Downtime is the other number that hurts. Our MoSi2 heating elements last for years of normal operation, and when one needs replacing, it’s a quick swap that your own technicians can handle. For facilities that require it, we build to UL and CSA certified electrical standards so your unit clears inspection without a fight.
Trusted by Demanding Operations
Custom furnaces from Sentro Tech are a must-have for several applications, including:
- Laboratory Research
- 3d Printing and Additive Manufacturing
- Mining and Smelting
- Heat Treating
- Battery and Ceramic Production

Names like NASA, 3M, GE, and Dow Corning have put our equipment to work. Everything is manufactured in the USA at our Ohio facility.
How the Custom Process Works
Our approach to custom industrial furnace manufacturing keeps you involved at every step:
- It starts with a conversation between your team and our engineers about your application, specs, and constraints.
- From there, we recommend an approach and send a design mock-up for your review and approval.
- Once your furnace is built, we invite you to our headquarters to inspect and test it and train your technicians before it ships.
- After delivery, we stay on for maintenance guidance, replacement parts, and service through the life of the equipment.

Custom Furnace FAQs
How long does a custom furnace take compared to a standard model?
Standard configurations are stocked for quick delivery. Custom builds take longer because they move through engineering, design approval, and fabrication first. Timelines depend on complexity, size, and features, so send us your specs, and we’ll scope a date based on our current build schedule.
Will a custom furnace need three-phase power, or can it run on single phase?
Most Sentro Tech models run on 208/220V single-phase. Larger, higher-power chambers, such as our 1200°C box models, require three-phase. Because a custom unit’s draw depends on chamber size and wattage, we confirm the electrical requirement during design so your facility’s supply is sorted before the furnace arrives.
Can you build to our lab or plant’s safety and compliance requirements?
Yes. We can specify UL- and CSA-certified electrical components when your site or insurer requires them, and safety features like the door interlock and an independent over-temperature controller are available to protect operators and products.
How long do the heating elements last, and what does replacement cost?
Under normal operating conditions, MoSi2 elements last for years, and some customers go a long stretch without a replacement. When they do wear out, the cost of the element depends on its size, and they’re designed for easy in-house replacement.
Do you support the furnace after it is installed?
We do. We advise on maintenance, supply replacement parts, and provide service throughout the furnace’s working life, so you’re not left to your own devices once the furnace is on your floor.
