Petrostar Receives Canadian Industrial Design Registration from Canadian Patent Office for Its ETH Zero CO² Technology...

Petrostar Petroleum Corporation (TSX-Venture: PEP, Frankfurt: LMQ; "Petrostar" or the "Company") announces that on June 17, 2009 it has received from the Canadian Patent Office, Industrial Design Registration (#128039), and protection for its proprietary ETH (Electric Tank Heater) technology.

The ETH unit is capable of replacing current burner tube tank heating devices and has a zero CO² emission signature as well as the potential of reducing operating costs by using power generated from top drive motors and eliminating the fuel requirements of the burner units for those batteries that are not running on electricity. The ETH technology is currently CSA compliant for field replacement and is currently undergoing testing to receive CSA mass approval for installation at the manufacturing and construction stage. The CSA tests, (Flameproof, Hydrostatic and Explosion Pressure Tests), are expected to be completed by mid July with approvals anticipated shortly thereafter. The Company has made a number of initial contacts with production and sales tank suppliers and manufactures to introduce the product to them as an alternative to the current burner tube installations.

The Company will also produce and make available a dual ETH control panel which will allow 2 units to be run in tandem and incorporate a power phase control that supplies power on a rotating basis to the heating unit. This provides a better distribution of heat to the tank and circulation of the emulsions stored within them.

The Company has also measured and monitored the reduction of CO² that is produced by tank units that are currently using the burner tube equipment to maintain production and sales tank heating.

The burner tube systems using propane or natural gas fuels produce quantities of CO² in the range of 14kg-25kg/day into the atmosphere whereas the ETH produces zero. This may be the most important factor in making this system a valuable commercial product. The reduction of CO² emissions is and will become increasingly important as regulatory agencies will seek to impose penalties on those who do not voluntarily reduce their emissions.
