The document outlines various connection options for the HMC and HMC-MINI series coil heaters, including PTFE insulated nickel leads and different protective features such as glass silk insulated sleeving, braided metal sleeving, and flexible metal sleeving, all with ground wires.
The coiling scheme for the HMC and HMC-MINI series includes options for tight coils, coils with a constant pitch, and coils with differentiated power distribution. The heaters can be supplied straight and coiled or bent later, but only once, following specific bend radius guidelines.
High precision stainless steel reflection tubes enhance heat exchange and mechanical protection. These are applicable to all sections of the HMC and HMC-MINI series, with customizable diameter, length, and coiling schemes.
The HLS product line offers a variety of heaters, including cartridge heaters, microtubular heaters, and nozzle heaters, available in stock. The document highlights the availability of different models and the option for urgent production through the FAST SERVICE line, which ensures delivery within five working days.
FAST SERVICE is a dedicated production line for non-standard cartridge heaters, allowing for quick production based on customer specifications. This service is designed to address urgent needs, such as production line stoppages or exhibition preparations.
