Follow our development

Vision

To become one of North America’s leading manufacturers of air handling units and the largest integrator of reverse-flow energy recovery systems, in a rewarding environment that fosters employee growth.

1980

Accubloc invented in Switzerland

1985

Drawings and specifications acquired for Sun Dog Manufacturing (SDM) direct-fired units

1991

Drawings and specifications acquired for DT (Weather-Rite) heat exchangers

1999

Manufacturing begins on SDM direct-fired express products

2001

Patent granted for TEGA CTW and CTU multistage heat exchangers

2005

TEGA Technologies acquired by BFL Group

2007

Manufacturing begins on our LDE gas-fired fresh air unit

2009

Nagas Innovation is created as an entity dedicated to producing gas-fired heat exchangers. The logo and name are inspired by the legendary sea dragons of Indian mythology

2015

Market release of our DTH high-turndown heat exchanger/burner

2017

Market release of our DTHC condensing heat exchanger

2018

Manufacturing begins on our DTHE gas-fired fresh air unit

2018

Shift from a gas heating model to heat recovery and decarbonization of fresh air heating.

We move away from gas heating markets to focus our efforts and research on heat recovery

2019

Licensing agreement signed with Polybloc to manufacture Accubloc in North America

2020

New 30,000-square-foot facility built to manufacture all the group’s gas products

2021

Production begins on high-efficiency (90%) Accubloc systems using an automated assembly line

2021

Drawings and specifications purchased from GP Combustion, an Ontario gas-fired burner manufacturer

2022

Manufacturing begins on SBE, our first 100% fresh air unit not heated by gas

2022

Exclusive distribution agreement for Accubloc signed with six major air handling unit manufacturers

2022

Announcement that the plant will be expanded to 70,000 square feet

2023

Second automated assembly line for Accubloc purchased to handle growing sales

2023

New SBE products added. Product line expands with five new models ranging from 1,500 CFM to 18,000 CFM

What’s next?

We are planning to boost production of fresh air heating products using high-efficiency heat recovery of over 90%. 

Air handling units with Accubloc technology greatly reduce the use of fossil fuels (natural gas, propane, or coal) for generating electricity. 

In a number of fresh air heating settings, it is even possible to completely eliminate the need for a heat source when preheating fresh air in plants or warehouses.
