NSL is a proud American family owned and operated business that works hard to keep profits local through working with regional small businesses.

Product quality is #1. Our generators are built to the highest standards. Our factory has all relevant quality manufacturing and testing certificates:

BUILT TO LAST:

ENGINEERED AND TESTED TO LAST OUTDOORS FOR 30 YEARS. THE SILENT ENCLOSURE IS HEAVY GAUGE GALVENIZED STEEL THAT IS POWDER COAETED. ALL HARDWARE IS STAINLESS STEEL. WE DON'T CUT CORNERS BY USING CHEAP ALUMINUM OR PLASTIC LIKE OTHER MANUFACTURERS.

ISO:9001 QUALITY CERTIFIED.

To become certified, a company hires a third-party firm to audit its processes, services, and products. The auditors measure the proper specifications and determine whether or not the organization meets the ISO 9001 criteria.

ISO:17025 CERTIFIED LABORATRY.

This is an international standard that sets requirements for the competence and consistent operation of testing and calibration laboratories. It's the main standard used by most laboratories in order to be considered technically competent and to gain accreditation in most countries.

ISO:8528 CERTIFIED PRECISION.

As a certification, defines various classifications for the application, rating and performance of generating sets consisting of a Reciprocating Internal Combustion (RIC) engine, Alternating Current (a.c.) generator and any associated control gear, switchgear and auxiliary equipment.

ISO 8528-1:2018 applies to a.c. generating sets driven by RIC engines for land and marine use, excluding generating sets used on aircraft or to propel land vehicles and locomotives.

For some specific applications (e.g. essential hospital supplies, high-rise buildings), supplementary requirements can be necessary. The provisions of this document can be the basis for establishing any supplementary requirements.

For other reciprocating-type prime movers (e.g. sewage-gas engines, steam engines), the provisions of this document can be used as a basis for establishing these requirements.

Generating sets meeting the requirements of this document are used to generate electrical power for continuous, peak-load and standby applications. The classifications laid down in this document are intended to help understanding between manufacturer and customer.

We are a Certified Cummins OEM factory. That means that our factory builds generators for Cummins! We have been trained by Cummins to build to their specifications and quality standards.

BEST PARTS USED:

We carefully chose every part used in each generator. The parts used are chosen based on quality and reliability track records;

We choose to use Stamford Brushless 4 pole Alternators which we have experienced that these will last longer than other brands and models.

The engines are carefully chosen brands and models that we know will last longer and require less maintenance than what is offered by the competition. We choose engines based on quality and longevity, not cost and emissions like other generator manufacturers. The engines we use have a long track record of reliability and are fully mature in their development and parts supply. Most other companies will choose the smallest engine that they can get away with. Not us. We choose the best candidates only, regardless of size, weight, or cost. We have a long list of approved engines that we supply, and we let the customer choose which they prefer after we give them all of the facts.

Hardware: We use all high grade stainless steel hardware on the generator enclosures.

Enclosures:

Our Enclosures/cabinets for silent/ Weather-proof generators, are heavy gage steel that is zinc plated, then powder coated to resist corrosion, rust, dents and dings. This is done to ensure our generators last many years outdoors in any climate.

The Enclosures are also heavily insulated for sound to make the generators run quietly in gated communities and near hospitals.

Testing:

Each generator is tested for 2 hours before delivery to the customer. We will not ship a generator unless it passes a battery of tests to ensure the highest standards of quality and reliability. Multi-million dollar equipment is used to test each generator. Load testing at 25%, 50%, 75%, 100% and 110% of load to ensure stability of voltage, HZ and other factors at increasing and decreasing loads. We test all of the alarm functions and sensors of the generator to ensure that the generator will shut it's self off if there is a problem, and report the problem to the owner on the controller screen.

Compare and Contrast.

We regularly compare our products to that of the competition, to make sure that we offer real value. Our company is confident that the buyer cannot find an equal or better machine for equal or lower cost. I promise that the buyers or our equipment will not have regretted their decision to buy from us, after comparing what he/she received to another company's product. Please see for yourself that our generators are the right choice for anyone, no matter size, type, or use case.
