Name: HST - PT 21.1B (2004)
Brand: HST

Question 1

What condition is this pre-owned PT 21.1B in?

Accepted Answer

The machine was manufactured in 2004 and inspected by dph International. A mechanical and electrical assessment is completed before listing, and an inspection report and available commissioning history can be shared on request. Refurbishment, parts, installation and training can be quoted separately.

Question 2

Which bag format does this machine produce?

Accepted Answer

The B bag format measures 40 × 60 mm and is widely used for double-chamber teabags in Middle East and European retail formats. The standard E1 tag is 23 × 28 mm, while E2 at 28 × 32 mm is available on request. dph can assess whether another format is feasible.

Question 3

What output can I expect?

Accepted Answer

Output reaches 175 double-chamber teabags per minute, equivalent to approximately 84,000 bags in an uninterrupted eight-hour shift. This matches the rated output of the current PT 21 series at lower capital cost. It suits growing producers that need capacity without a new-machine manufacturing lead time.

Question 4

Is cartoning included?

Accepted Answer

Yes, automatic single-row cartoning packs finished bags directly into cartons. This creates a more complete line and reduces manual secondary-packaging labour. Carton format should be confirmed during inspection.

Question 5

What utilities does the machine need?

Accepted Answer

The machine requires a 1 kW electrical connection, approximately 0.65 kWh consumption and compressed air at 4–6 bar. Installed dimensions are 240 × 100 × 195 cm and weight is 1,035 kg. dph can provide a complete installation checklist.

Question 6

Are spare parts still available?

Accepted Answer

Yes, the HST PT 21 series remains in active production, supporting continued mechanical and electrical parts availability through HST and dph. Active-series support reduces the extended downtime risk associated with obsolete machines. Parts requirements can be reviewed during inspection.

Question 7

How can I inspect the machine or request more information?

Accepted Answer

dph can provide documentation, photographs and current availability from its Dubai office. A video inspection allows the buyer's technical team to review condition before arranging a visit. dph can also quote logistics, commissioning and operator training.

Question 8

What is the advantage of buying pre-owned over new?

Accepted Answer

A pre-owned HST PT 21 can deliver comparable rated output at lower capital cost and without a new manufacturing slot. This helps producers add capacity quickly for a season or contract. dph can provide refurbishment, parts and technical support to reach the required operating condition.

Question 9

What teabag filter paper and consumables does it use?

Accepted Answer

The HST PT 21.1B uses flat filter paper for double-chamber bags with thread, tags and envelopes for its knotted format. dph stocks Magnera filter paper, Interfil thread and Gundlach tags in Jebel Ali, Dubai. dph can confirm the exact grade and dimensions for this configuration.

Question 10

What warranty or after-sales support is available?

Accepted Answer

dph supports supplied pre-owned equipment with parts access, remote service and on-site visits across the Middle East. Original manufacturer warranty does not apply, but dph can quote preventive maintenance and priority-parts agreements. The package is defined according to machine condition and buyer requirements.
