Inverter-controlled preheater
We have been delivering our preheater (Q5 series) for more than 30 years since we developed the first model with our original technology in 1993. After launch, we've been taken customer's opinion into consideration and built on improve usability, to say nothing of performance. Therefore Q5 series receive high evaluation and repeat order from customers. The Q5 Series is available in three models, according to wire size: single wire φ0.25 to φ3.8 mm and stranded wire 0.05 to 8.0 sq.
Product Features
1. Abundant variation
Three models are available for wire sizes: single wire φ0.25 to φ3.8 mm and stranded wire 0.05 to 8.0 sq.
2. Energy saving
The power supply is a three-phase power source that is once converted to direct current internally, resulting in low reactive power and economical running costs.
3. Line speed following
The line speed follows the line speed from 20 m/min and the heating temperature of the wire is controlled so that production quality can be maintained at the same level as the normal production speed during start-up and shutdown, thereby reducing wire loss.
4. All season
Constantly monitoring ambient temperature,
5. Ease of operability
By setting line size, line speed, and temperature conditions on the touch panel, operation can be started without making fine adjustments during production. Also, by recalling the conditions registered on the recipe screen, reproducible operation can be started in a short time, regardless of the operator’s skill level.
6. Space saving
The use of an 800HZ high-frequency transformer makes the entire device compact and can be installed in a minimum amount of space.
7. PLC control
The use of commercial PLC for temperature control shortens shutdown period when breakdown, and it makes possible to setup optional multistage control of production speed according to conditions at start-up and shutdown.
8. Temperature feedback control (option）
The standard type without feedback control can be controlled within -5% of the set value, but the program is based on the electrical resistance at 100% copper. Depending on the electrical resistance of the conductor, there may be an error in the set temperature, or the actual temperature at crosshead entry may be lower than the set value due to heat radiation depending on the wire size and wire speed.
To further improve quality, a non-contact thermometer (purchased externally) can be attached to the outgoing part of the preheater to measure the conductor temperature and correct the preheater current value to produce a conductor surface temperature close to the set value.
