Purchase of Gas Cylinders

Descriptions

•Must be able to pick up and either refill, or provide replacement cylinders as and when we consume the gas inside them, •Must be able to provide regulators so we can both monitor gas flow (pressure being delivered from cylinders) and to show how much gas is remining in the cylinder, •Must be able to do this for all depots in the NGN area on and ongoing contractual basis, •Would like if can provide larger quantities of cylinders should we have a gas incident and want to use the technique in place of fan heaters and hot plates, but this is not essential.
