Conserval Engineering (based in Toronto) is now producing the SolarWall 2-Stage system for windy locations and roof-mount projects. As in the original SolarWall technology, outside air is heated and drawn into an air cavity via tiny perforations in the collector. With the 2-Stage system, the air is heated a second time as it passes behind the top glazing. Conserval also has a 2-Stage version of the SolarDuct Rooftop heating system.

Lennox’s multi-stage air volume (MSAV) supply fan technology for installation on light commercial rooftop units enables lower airflow during four conditions: part-load cooling, heating, ventilation and free cooling operation modes. The technology dramatically reduces energy costs. Airflows can be customized with simple changes to the Prodigy unit controller. MSAV is also available in T-Class large split system units.

The Mini Canal radiator from Jaga Canada Climate Systems (photo right) is a simple and compact underfloor design that allows only the grill to be visible. Under the grill is a fast Low-H2O element, which conserves more energy while emitting maximum heat.


GE has launched two new products for utilities. The PowerOn Precision demand response management system allows GE utilities to manage peak demand and provide support for grid stability. The Multilin Intelligent Line Monitoring System is an end-to-end monitoring solution with advanced analytics for overhead electric distribution networks. It improves network reliability by providing information on faulted and soon-to-be-faulted circuits.


Advanced Drainage Systems has a new storm water trap. The Nyloplast EnviroHood Structure is readily attached inside a manhole or catch basin to trap debris, oil, and other sediments. It is made from HDPE and has corrugated ribs.


Bentley Systems has acquired Ontario-based Ivara Corporation, which makes asset performance management software. The Ivara software is primarily for asset-intensive industries, such as mining and metals, power generation and utilities, oil and gas and petrochemical industries.
