HTMP SERIES

COMBINATION
MULTI-PASS
FOR TIGHT
SPACES
HTMP multi-pass tanks accommodate tight space demands for
high speed, high rate medical tubing production. High technology
vacuum sizing is integrated with servo driven multi-pass sheaves
within the primary cooling tank to satisfy product-specific residence times while precisely cooling and metering the product.
Ideally designed for cleanroom and other space limited production
areas, the HTMP delivers the industry’s best control over medical
product sizing, ovality, tolerance and tension for flexible PVC, TPE,
TPU and PE tubing.

Model HTMP 18-4

ELIMINATE STRETCH AND TIGHTEN TOLERANCES
HTMP combination multi-pass tanks are
designed for high-speed commodity
tube extrusion requiring extensive bath
cooling. The multi-purpose tanks take up
to five times less floor space compared
to standard cooling tanks. HTMP tanks
incorporate a vacuum (or free extrusion) chamber and feature a servo-driven 20-inch {508 mm} diameter primary
sheave that doubles as a puller. The
large diameter and controlled pull force
avoid tube flattening and distortion.
Sheaves can be machined to a particular
tube diameter, improving accuracy over
belt pullers by eliminating the normal
‘crush’ effect. The driven sheave significantly shortens the travel distance of the
tube before pickup, minimizing stretch
and tension.
Precision glass bearings on non-driven
sheaves reduce drag and stretching as
the tubing makes subsequent passes
through the tank at line speeds that can
approach 800 feet/minute
{243 meters/minute}.

■

Improve process control
Supplied with an integral vacuum chamber, the HTMP adds critical stability to
the process by holding precise and repeatable ovality, concentricity and wall
thickness. Vacuum can be held to 0.10 inches of water {0.19 mm mercury}.
Seamless controls integration with third party measuring systems ensure
repeatability.

■

Integrated components save cost
The HTMP integrates a precision vacuum tank, primary puller, multi-pass cooling
and air wipe chamber into a single package, eliminating added cost and space
requirements for stand-alone components.

■

Cut material waste and increase yield
Precision vacuum combined with a third party ID/OD gauge provides exceptional
dimensional control to save tens of thousands of pounds of material while
increasing production yield. Example: Systems have reduced tolerances from
±0.005 inch {±0.127 mm} down to ±0.003 inch {±0.076 mm}.

■

Cleaner interior design
Tank interior is designed to ease daily cleanout by minimizing sharp corners and
exposed threads where bacteria, pyrogens and other particulate matter can build
up. Telescoping drip tray is one piece to aid wipe-down by eliminating open
seams. Guide rollers inside the vacuum tank are fixed to free-standing mounts to
allow removal for cleaning.
