Compartment Tanks are designed to store multiple grades of product, or different types of products, in the same tank. This safe, economical alternative allows you to create multiple fuel storage compartments without having to install separate tanks for each product. They are available with single or double bulkheads and are ideal for storing multiple grades of gasoline. Diesel and biodiesel blends can be stored in the same tank. Advantages include easier installation, requires less space, reduced shipping, excavation and insurance costs. Download brochure.

Highland EZ Access

Highland Tank’s high-perfromance oil/water separators are also available with the EZ-Access System. The system is designed for easy access to the removable parallel plate and PETRO-SCREEN coalescers contained within the separator.
Observation, maintenance and cleaning can take place without having to empty the separator or send personnel inside. Separators are configured with one or two rectangular access chambers to allow total, unconfined, unrestricted top access to the separator’s internal parts. Highland’s EZ-Access system meets OSHA’s requirements on confined space entry into a vessel containing harmful fumes.
