A workshop needs two kinds of time information before it can plan a cylinder-filling appointment. One is the expected time for the proposed job. The other is the maximum interval the compressor maker specifies for continuous operation. The HEAP-1 catalogue provides both, and they belong on separate lines of a quotation.
Write down the reference conditions
The HEAP-1 product table gives approximate filling estimates of 11, 21 and 45 minutes for the stated 0.5 L, 1 L and 2 L examples, respectively. The table describes a starting condition of zero and an endpoint of 200 bar for those examples. The listing separately states a maximum continuous run time of 30 minutes and refers readers to the model instructions for longer jobs. These are published catalogue figures. Their use here is to identify the questions a workshop should settle when assessing the purchase.
The 2 L row is useful precisely because the reference duration exceeds the listed continuous interval. An estimate for the job may depend on cooling breaks and the conditions in which the figure was obtained. Ask the seller to clarify what the 45-minute reference measures and obtain the current HEAP-1 instructions for the exact version offered. Leave the total elapsed time open until the basis for that estimate is clear.
Keep the receiving equipment in the worksheet
The T-2000 manual describes a particular receiving assembly, including its gauge, filling connection and model-specific requirements. Keep that information alongside the compressor documents if a T-2000 is under consideration. The catalogue’s use of a 2 L example tells you the example capacity. Approval of a particular compressor, receiving cylinder and connection needs separate evidence from the relevant documents and a qualified fill provider.
Build a service-time request
- Identify the compressor version, the receiving cylinder model and the conditions the qualified provider proposes to assess.
- Ask what the estimate measures, including any cooling intervals, preparation time and separate handling time.
- Request the current manual and written clarification of how the quoted conditions were established.
- Record the expected elapsed service window separately from the documented continuous operation limit.
That separation lets a buyer compare a machine with a local fill service on a useful basis. The provider can assess the complete arrangement and whether the intended work fits its schedule and procedures.
Ask TRIMIX for the HEAP-1 document set and estimate assumptions with the exact receiving equipment and proposed service context.
