Middlesex Gases


Our Service Advantages

Specialty Gas Experts in New England

Our large fleet is our main advantage

Middlesex Gases’ primary focus is to provide the gases and equipment customers require in a timely manner. To accomplish this, we continue to invest in and expand our fleet of trucks in order to satisfy the wants and needs of our customers.

Whether you require bulk, MicroBulk, liquid dewars or high-pressure cylinders, Middlesex Gases has the ability to deliver directly to your location. We have an extensive fleet of 10-wheel box trucks and box trailers for your high-pressure and portable liquid dewar needs. Adding the box trailers to our fleet gave us 50% more space to deliver highly-demanded liquid dewars. In addition, having an enclosed truck keeps the cylinders clean when delivering into labs and clean rooms.

For your bulk and MicroBulk requirements, we have bulk trailers ranging from 4,200 gallons to 7,800 gallons. Our bulk and MicroBulk fleet allows us to handle a full range of tank sizes from 1,000-liter MicroBulk tanks all the way up to 13,000-gallon bulk tanks.

In some locations a bulk trailer is too large to deliver into smaller confined spaces, which is why we have smaller 10-wheel bulk trucks available to service these customers.

We hear stories like Lilly’s all the time

Lugging around heavy dewars, spending sleepless nights worrying about the cryo-freezer going down, and putting up with inefficient, outdated monitoring systems and unreliable service are just a few of the reasons why Lilly, a local lab technician, needed to change specialty gas suppliers.

Listen to her story to learn how Middlesex Gases helps her keep the gas flowing, so she can focus on more important things.
