Operating guidance for the Techspan Transsonic TI-H range of ultrasonic cleaning units —
TI-H 5, 10, 15, 20, 25, 55, 80, 115 and 160. Taken from the operating instructions supplied
with the unit by Techspan.

Single-frequency and multi-frequency units
TI-H units were supplied in two variants, and which one you have determines what the controls do:
- SF1 — single frequency, 35 kHz. No frequency selector, no mode selector.
- MF2 — multi-frequency, 25 / 45 kHz. Frequency and function knobs are fitted.
Check the nameplate if you are not sure. The degas and Sweep functions described below apply to
multi-frequency units only.
Frequency selection (multi-frequency units)
- 25 kHz — removing coarse and tenacious contamination, and pre-cleaning robust
surfaces. - 45 kHz — fine cleaning and removing contamination from sensitive surfaces.
The frequency can be changed while ultrasound is running.
Standard and Sweep modes (multi-frequency units)
Set at the function knob, and switchable during operation:
- Standard — use when the basket is connected to a manual or automatic oscillation
device. - Sweep — continuously shifts the sound-pressure maxima for a more homogeneous
sound field. Use this when the basket is not on an oscillation device.

Safety and maintenance
- Solvent-containing and aqueous cleaners both have limits on use — check section 8 of the manual
before introducing any new chemistry. - On TI-H 25 and larger, the safety switch-off must be checked periodically.
- The transducer tank is a wearing part; service life depends on the media used and how the unit is
run. - Repairs must be carried out by authorised personnel only.
Support and replacement
The Transsonic TI-H is a legacy range. We continue to support units in the field in New Zealand
and can advise on servicing, consumables, baskets and a current-model replacement sized to your
existing tank. Call 0800 603 603, email
info@elma-ultrasonic.co.nz, or see
service & support.
For a like-for-like size in the current range, look at the
Elmasonic X-tra series for bench units and the floor-standing
X-tra ST series for the larger TI-H tank sizes.
Before replacing a unit that seems weak, confirm it with a
SonoCheck activity test vial.
