Welcome to Convectronics:

A premier US manufacturer of first-class heaters, temperature sensors, and controls. We offer a wide variety of industry standards available for "just in-time" delivery.

Convectronics provides engineering support and service to ensure your custom products are of highest quality.

Air Heaters

Air Heaters Air Heaters

Convectronics’  air heaters are designed to meet and exceed all expectations:

  • Temperature up to 1500°F
  • Clean electric heat without the flame
  • Compact size with rapid heat-up and cool-down
  • Controllable by varying voltage, flow rate or temperature controls
  • Excellent repeatability
  • Directable heat
  • Easy installation

Tubular Heaters

Tubular Heaters Tubular Heaters

Convectronics’   tubular electric heaters   can be formed into nearly any configuration.

Auto manufacturing is just one industry that requires unique shapes and durable construction — like the heater used to shape the materials for creating a car door.

Convectronics’ temperature sensor products conform to applicable ISA standards and provide accuracy traceable to the National Institue of Standards and Technology (NIST).


Controllers Controllers

Convectronics' controllers provide precision PID control of temperature and other processes.

Our controllers excel at providing uniform heating and can replace multiple interconnected devices, saving time and money.

Convectronics' temperature controllers are easy to use and customize. 

"I have been purchasing parts from this company for 6 years and never once failed me on their products. They also have an excellent customer services department."

- Brian B., Biomass RTD Customer

"I’d like to thank Leslie Lanctot and her team for their above and beyond customer service. We were stock out of a custom heater for one of our products and needed to ship to our customer in a few days. Leslie and her production team expedited my order from a 2-3-week lead time to just a few days. Thank you, Jim"

"Amazing service in all aspects, even for my most complicated orders! No matter what department I have interacted with, they have always gone above and beyond for me. They put a lot of time and dedication into what they do and it definitely shows. Thank you for always being so helpful and attentive."

"Leslie and the rest of the Convectronics team are great to work with - she went above and beyond in trying to resolve an issue and getting product shipped out as quickly as possible for our customer."

"A first rate company and a first rate product. On time delivery, quality products and backed up by top-notch customer service. I've been buying Convectronics products for nearly 20 years and have never had an issue."

"This is one of my favorite Manufacturers to work with. They take care of you the same day you ask for a quote or to have something ship really fast. It's always a delight to work with their customer service person, as they are always eager to take care of any issues that might come up."
N. Logan

"Excellent quality products! The entire staff provides great customer service and support. Highly recommend their products."

"They sell an excellent product which I know is true because I have never had a customer come back to us asking for a repair or a refund. Hats off to one of the best factories in the U.S.A. Thanks for your support, Nancy"

We Cover a Variety of Industries

Container Forming

Those plastic cups and utensils for your last cookout? Our heating systems and solutions enable the manufacturer to precisely control the temperature of the plastic as is it formed into those famous red cups and the plates that hold your burgers and hot dogs.

And those lids for your morning cup of coffee – what would we do without those?

Hot Runner Systems

Injection molding requires heating a variety of materials — including metals, glass, elastomers, and thermoplastic polymers — and injecting the molten material into molds for mass production of parts and components.

Convectronics manufactures a variety of tubular heaters and thermocouples for this process.

Pellet Mills

Convectronics manufactures  temperature sensors  that enable consistent monitoring of materials, surfaces, liquid temperatures, and more.

The wood pellets you may be burning this winter? RTDs created by Convectronics are used to measure and monitor the temperature of the rolls inside the pellet mills to achieve the optimal heat/moisture levels to produce the pellets.

Oil and Gas

The oil and gas we use to heat our homes and power our cars often come from offshore platforms that require keeping these elements at precise temperatures for storing, compressing, and transporting via pipelines.

Convectronics heating control systems enable oil and gas producers to precisely control the temperature as the fuel expands, contracts, and flows to the end users.
