RESILIENCE IS INNOVATION
Industrial Generators
Winter Engine - Generator continues to support the Consulting and Specifying Engineers throughout Eastern Pennsylvania. We appreciate the opportunity to participate in the design of Emergency Power Systems — when a project goes smoothly, it benefits everyone involved.
REHLKO® TOTAL SYSTEM INTEGRATION
A power system is only as good as the parts that define it.
This isn't your typical power system. A Rehlko® industrial power system is loaded with designed and manufactured components from Rehlko® — generators, transfer switches, switchgear, controllers, and more — all engineered to work together as a single, integrated system. We engineer every detail down to the last bolt.
WE'RE THE FULL PACKAGE
Integrated solutions backed by technical knowledge and local support
Industrial power projects require more than equipment alone. They require a knowledgeable partner who understands specifications, application requirements, serviceability, and the realities of installation in the field.
Winter Engine - Generator works with contractors, engineers, facility teams, and technical buyers who need responsive support, dependable solutions, and confidence in execution. From equipment selection to ongoing service, our team helps customers move projects forward with clarity, efficiency, and long-term reliability.

THE POWER BEHIND THE BACKUP
Transfer Switches
Transfer switches are industry-leading devices that safely transfer electrical loads between utility grids and backup generators. They are trusted in residential, commercial, and mission-critical applications to provide seamless power transitions, protecting facilities when utility power fails.
Two types of Transfer Switches
Automatic Transfer Switches (ATS) primarily differ from Manual Transfer Switches (MTS) in their operation. ATS automatically sense power failures and switch the electrical load to a backup generator without any need for human action. In contrast, MTS necessitate a person to manually operate a lever or toggle to change the power source.
How do I know which one I should choose?
Manual Transfer Switch
When power outages occur, businesses can face significant challenges. For smaller organizations or businesses, investing in a permanent generator may not be financially feasible. Manual transfer switches are a more economical choice, with the caveat being that someone must be physically present to flip the switch when the power goes out.

Brands we carry
Quality, reputation, and experience are important to us at Winter Engine - Generator. Therefore, the products and brands we represent must be of the highest value to us and to you, our customers.
ASCO Power Technologies was founded in Baltimore in 1888 and introduced the first Automatic Transfer Switch in 1925. Throughout the years, ASCO pioneered many of the designs that are still used today. They've been around a long time, building a legacy of trust and service -- something we wholeheartedly relate to.
Winter Engine - Generator proudly offers a comprehensive selection of both Rehlko® and ASCO® Transfer Switches to meet the diverse needs of our clients. Our commitment to excellence drives us to provide ASCO Automatic Transfer Switch (ATS) and Switchgear, ensuring that we can cater to the unique requirements of each project. By offering these products, we guarantee that we are equipped to fulfill specific engineered prints and specifications, particularly in cases where Rehlko does not meet the desired criteria. Our goal is to deliver reliable solutions that enhance the performance and efficiency of your power systems, ultimately supporting the success of your operations.
