We supply cylinders for gaseous helium and technical gases in various volumes (from 4 to 50 liters). Our specialists organize delivery, refilling if necessary, and will help select the optimal solution for medical institutions, industrial enterprises, and the event industry.

Mobile multi-element gas containers are designed for transporting technical gases and consist of a frame structure with a bundle of 12–16 standard cylinders (40 or 50 liters each), integrated into a unified system with pipeline connections.

Multi-element gas containers are designed for the transportation or stationary storage of technical gases. They feature a frame structure with a bundle of 4–7 large-volume cylinders (400 to 650 liters each), combined into a single system with pipeline connections.

Vacuum-insulated Dewar vessels (40–1000 liters) for secure storage and transportation of liquid helium and nitrogen. These compact solutions are in demand in scientific laboratories, universities, and small medical facilities. We provide professional storage and transportation solutions for cryogenic liquids, including the CMSH series of vessels:

CMSH 250 (Standard)
CMSH 250-S (Air Transport)
CMSH 500
CMSH 1000

All CMSH series models feature:

High-quality vacuum insulation
Reliable pressure control system
Compliance with international safety standards
Customizable configurations
