Enermax Mountain Manufacturing is an ASME “U”, ASME “S”, and National Board “R” Certified Manufacturing shop, located in Maple Ridge, BC. We specialize in the Design, Fabrication, and Repair of ASME Section I and Section VIII Div.1 Shell and Tube Heat Exchangers, Pressure Vessels, and ASME B31.1 and B31.3 Industrial Piping. We also have the capabilities to manufacture API 610/650 Tanks, and various custom fabrication assemblies. We have the expertise and the weld procedures to fabricate projects ranging from Carbon Steel to Titanium, and everything in between.

We employ our own in-house design team, consisting of Professional Engineers and other technical experts, who work directly with our customers, ensuring all custom fabrication services comply with the applicable customer specifications and design codes.

Our customer base includes companies involved in several industries: Oil & Gas (Parkland Refining, Enbridge, Tidewater Midstream, Imperial Oil, Nova Chemicals, Suncor, Phillips 66, Fortis BC), Pulp & Paper (Domtar Kamloops Mill, Paper Excellence, Canfor), and Chemical (Chemtrade, Erco). 

Our Story

In 2002, Enermax purchased Mountain Manufacturing. It was formed as the product of a merger between Enermax Fabricators Ltd. and Mountain Manufacturing Ltd. Enermax Fabricators was founded in 1978 as an ASME certified fabricator specializing in the design and manufacture of high quality tube and shell heat exchangers and other pressure vessels. Mountain Manufacturing, founded in 1985, was a precision machine shop that offered mechanical fitting and repair services. Both companies were founded in North Vancouver, Canada.

In 1998 the original owner of Enermax was looking to retire and sold his company to our current ownership group. Enermax flourished under new ownership and in 4 years purchased a neighboring machine shop, Mountain Manufacturing. The two companies remained separate entities until our Maple Ridge facility was completed. Shortly after both companies moved under one roof and formed EM Manufacturing.

Today EM Manufacturing operates in the same spirit of quality craftsmanship as its counterparts did, but now offers the added benefits of an improved facility, modern CNC equipment and the combined services of both companies.

Engineering & Design Excellence

As a premier pressure equipment manufacturer, Enermax delivers high-performance solutions engineered for the most demanding industrial environments. Our commitment to excellence begins with a custom-first approach. Unlike providers who rely on standard catalogue parts, we operate as a true custom heat exchanger manufacturer. Utilizing in-house P.Eng expertise, we optimize thermal designs for maximum efficiency. Our team navigates complex regulatory standards, including TEMA, API 660, and CSA B51, ensuring every shell and tube heat exchanger fabrication is fully compliant and audit-ready through advanced performance simulations.

Fabrication & Facility Strength

Our industrial fabrication capabilities are anchored by a wide spectrum of material expertise, ranging from carbon steel to exotic alloys for corrosive applications. As an ASME pressure vessel manufacturer, our strategic location near barge access and the US border allows us to manage oversized logistics for Western Canada and the Pacific Northwest seamlessly. Through vertical integration, we control the entire process, from plate rolling to final assembly, eliminating third-party delays and ensuring your project stays on schedule.
