Integrated Steam Shrink Machine
T2020 Integrated Steam Shrink Machine
A self-contained steam shrink machine for sleeve labeling lines. The 24 kW electric steam generator, shrink chamber and conveyor are built into one unit — connect power and water, and the machine produces its own steam.
Key Advantages
Self-Contained Steam Generation
A 24 kW electric steam generator is integrated in the machine — no external boiler, no steam piping, no separate steam source on site.
Integrated Conveyor
A 200mm width stainless steel chain conveyor is built in, with stepless speed control from 0 to 12 m/min — the machine works as a standalone shrink station.
360° Steam Coverage
Ten steam nozzles with adjustable angles surround the container path, so the sleeve is heated evenly across the full circumference.
Compact Single Unit
Steam generation, shrink chamber and conveyor in one frame of 1700 × 850 × 1500 mm, weighing 150 kg net.
One Machine, Two Site Connections
T2020 is an integrated steam shrink machine for sleeve labeling and shrink sleeve packing. Because steam generation and conveying are built in, the unit only requires a power supply and a water line at 0.4 MPa — it can be installed inline with a filling line or operated as a standalone shrink station.
Typical applications include sleeve labeling and shrink sleeve packing for bottled water, beverages, juices, dairy products, condiments, pharmaceuticals, nutraceuticals, household chemicals and cosmetics.

Steam Shrink Technology for Sleeve Label Applications
Steam is a widely used heating medium for shrink sleeve applications because it transfers heat evenly across the curved surface of the container. Unlike convection or radiant heat, steam conforms to the product geometry, allowing consistent contraction of the sleeve material.
T2020 works with saturated steam at 100 °C and a working pressure of 0.1 MPa, distributed through ten nozzles arranged around the container path. For the complete machine range and technology overview, see Tengyi’s steam shrink tunnel solutions.
Integrated Steam System
The built-in steam generator is rated 24 kW — a 6 kW preheating tank followed by 18 kW of main steam power — and produces steam within 5–8 minutes of switch-on, with a water consumption of 32 L/hour at a 0.4 MPa supply pressure.
Staged Heating
Preheating tank 6 kW + main steam 18 kW, with 50 W standby consumption.
Unattended Operation
Automatic water refill, low-water protection and overpressure protection as standard.
Engineering Design Explained
The T2020 machine configuration is based on four engineering design features, described below.
Integrated Stainless Steel Chain Conveyor
A 200 mm stainless steel chain conveyor runs the full length of the machine, driven by a 60 W motor with stepless speed control from 0 to 12 m/min.
- Design: Stainless steel chain belt, 200 mm wide; conveyor height customizable.
- Benefit: Standalone operation without a host machine; speed matched to the required shrink time; maximum load 1 kg per product.
Compact Integrated Frame
The shrink chamber (L1300 × W200 × H200 mm, 180 × 200 mm effective shrink area) sits directly above the conveyor inside a single 1700 × 850 × 1500 mm frame.- Design: Steam generator, shrink chamber, conveyor and electrics in one frame.
- Benefit: 150 kg net weight, no foundation work, short steam path inside the machine.
Ten-Nozzle Steam Distribution
Ten steam nozzles form a single shrink zone with 360° coverage around the container path. Nozzle angles are adjustable, so steam can be directed to the areas of the container that contract most.
- Adjustment: Nozzle angle adjustable; one controllable shrink zone.
- Benefit: Even sleeve contraction around the full circumference of the container.
Operational Protection & Continuous Duty
Steam generation, water supply and safety interlocks are handled inside the machine. The electrical system is deliberately simple — no PLC and no touchscreen — which keeps service requirements low
Automatic Water Refill
Water is replenished automatically during operation — no manual filling between shifts.
Low-Water Protection
The heating system is protected against operation with insufficient water in the generator.
Overpressure Protection
Steam pressure is monitored and protected, with a working pressure of 0.1 MPa.
24-Hour Continuous Running
Rated for continuous operation of up to 24 hours, with a 50W standby consumption when not heating.

Frequently Asked Questions
Does T2020 require an external steam boiler?
No. T2020 has a built-in 24 kW electric steam generator (6 kW preheating tank + 18 kW main steam), so no external boiler, steam piping or separate steam source is needed. A power supply and a water line at 0.4 MPa are sufficient.
How long does it take to produce steam after switch-on?
The preheating time from power-on to steam output is 5–8 minutes. Steam is generated at 100 °C with a working pressure of 0.1 MPa.
What water supply does the machine need?
A water supply at 0.4 MPa is required, with a consumption of 32 L/hour during operation. The machine refills water automatically and includes low-water and overpressure protection.
What production capacity can T2020 achieve?
The recommended stable capacity is 800–1,200 bottles per hour, with a maximum of 2,000 bottles per hour. Actual output depends on container size, label height and the conveyor speed setting between 0 and 12 m/min.
