Plate Heat Exchanger at Lonsdale Energy Corporation

The following photos of equipments (which include plate heat exchangers) and information are taken/supplied by Mr. Douglas Dunn from BCExplorer.org. Thanks for contributing/sharing.

It is about a system operated by Lonsdale Energy Corporation, a subsidiary of the City of North Vancouver BC, Canada. Lonsdale Energy Corporation or LEC is a wholly owned city of North Vancouver corporation working in partnership with Terasen Utility Services to deliver energy services to the Lower Lonsdale area of North Vancouver.

In 2004, the City retained the services of the Lonsdale Energy Corporation and their operating partners to provide a district energy service as part of its ongoing commitment to sustainability. The Lonsdale Energy Corporation (LEC) is a state-of-the-art heating system that delivers high efficiency energy to its customers. It uses a series of boiler mini-plants to circulate hot water and heat the buildings that are connected to the LEC system.

There are several units of plate heat exchangers in the company. All of the plate and frame units are manufactured by a Canadian based company called Armstrong. Armstrong also have branches in UK, USA, Australia, India and China. Check out the equipments utilized by LEC:


These 4 units provide Domestic Heating for Commercial and Residential buildings in the complex, they are equipped with flow monitors used to bill the customers for usage. The plate and frame heat exchangers are very clean and well managed.

This unit is connected to the primary loop for the boilers, as well as the district distribution network. The boilers are designed to use a variety of clean-burning fuels allowing LEC the opportunity to switch to more economical fuel sources.

Compact Plate Heat Exchangers for Refinery Heat Recovery

I stumbled upon an interesting article about compact plate heat exchanger which was published in engineeringnews.co.za. The article was about Compact Plate Heat Exchangers used for Refinery Heat Recovery:

The use of compact-plate heat exchangers (CPHEs) enables refiners to tackle the increasing emphasis on reducing energy consumption while maintaining a positive environmental profile, indicates a report by industrial process technologies supplier Alfa Laval.

CPHEs properties make them more efficient than, and provide a compact solution to, traditional shell-and-tube (S and T) heat exchangers.

CPHEs, which are much smaller in size than traditional heat exchangers and can be fitted in the footprint of existing installations, can increase capacity and recover more heat by using fewer heat exchangers.

Savings in fuel consumption and reductions in emissions, owing to greater energy recovery, give attractive investment payback periods.

Plate Heat Exchanger Is My Favourite Equipment

For this one month period, I'm going to focus my post more towards my favourite equipment in a processing / production plant - plate heat exchanger. I am very passionate and possess high interest in this equipment. A plate heat exchanger do not uses electricity and that's why it is also called economizer. The heat energy is exchanged from the hot fluid to the cold fluid in a very well and carefully arranged plates (between plate heat exchanger frame). How much kilocalaries or kW energy transferred really depends on the fluid inlet properties and the plate heat exchanger design.

For a start, I list out all of my previous plate heat exchanger related entries for your references. Then in future entries, I will slowly and progressively share my experiences dealing this interesting equipment.

Sometimes, I feel like switching my job and work for a heat exchanger company and make myself a plate heat exchanger specialist. But that position is very limited. Well, if you are still a student and plant to work with a heat exchanger related companies upon graduating, hold on to my blog for one month. I'll try my best to discuss about it (my version, my scope)....

I'm also working out to make a list of all plate heat exchanger companies, manufacturers, agents, distributors (all around the world) for easy reference. If you are one of them, please contact me and provide details of your products and company. I'll be very happy to include you in the list.
