Complete CHP-Units or Gas Upgrading Plants

NISSEN Power Modules (NPM), based on MAN’s modern and robust gas engines, are customized CHP-units designed and built in the NISSEN workshop. We specialize in designing user-friendly solutions with incorporated considerations for e.g. work environment. We have our own design studio, production and service department, which makes us the right choice if what you want is an energy solution designed as needed while meeting environmental and legal requirements.

Our membrane-based upgrading plants upgrades the raw biogas to natural gas quality (bion natural gas), which can be supplied to the natural gas network. Like our other product range, our upgrade system is delivered specially designed for each individual customer and their needs.

We are involved in all phases, from technical sparring to subsequent operational strategy – we want to maintain your investment through our good service, to create strong relationships and long-term collaborations.

Our customers are typically sewage treatment plants, cogeneration plants, farm biogas plants and other industries.
