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.
