Textile Industry
The original historical sector that LAGARDE® specialised
in and made its reputation Steaming standard autoclaves
of diameters between & 1300 and 1600 and a length adapted to your requirements
Other possibilities created upon specificities
Various applications
- Thermo-fixing of twisted yarns;
- Retraction of synthetic fibres ;
- Preservation of the shape of hosiery items;
- Preservation of dyes and printed designs- Humidity control and moisture recovery
- Two principals of steaming depending on goals researched
Classic steaming process
After an initial vacuum to vent the air excess present in the chamber and to aide the penetration of the steam in the textile material, a direct injection of steam allows the steaming of the textiles in an atmosphere saturated steam.
Steam injection is controlled along with the programmed temperature settings. During the temperature come-up time, an internal exchanger allows the steam to be heated and limits the production of condensation.
Intermediate vacuums to accelerate the penetration of the steam can be programmed. After the steaming, a final vacuum allows the textiles to be cooled and eliminates any excess humidity.
This principal can be used for all textile fibres: natural, artificial, synthetic and mixed.
Steaming process with moisture recovery
After an initial vacuum to vent the air excess present in the chamber and to aide the penetration of the steam in the textile material, a volume of water stored in the bottom of the autoclave is heated by “BUBBLING” or by electrical heaters.

The environmental conditions found in pharmaceutical autoclave chambers are extreme for any equipment. These conditions are a major cause of sensor failure in chamber/load probes, due to the ingress of moisture into the sensor and the unacceptable leakage of steam/condensate through the bulkhead connection.
The Sterimaster® Chamber/Load Sensor has been designed to withstand these conditions and offers a reliability factor surpassing anything previously obtainable. Every weld undergoes NDT examination and each completed assembly is leak tested.

Customer Requirement:
An RTD assembly was needed to monitor product temperature by piercing a sealed bottle within a sterilization chamber. When not monitoring product temperature, the assembly was also used to monitor internal chamber temperatures. Process temperatures reached 134°C.
Conax Design Solution:
Conax provided a 3-wire, 100 ohm platinum RTD assembly with a 4" long chisel point tip. The assembly consists of a sealed T3 termination, with 10 foot of treated silicone insulated cable that prevents moisture penetration, and a 0.125" diameter 316SST sheath. The assembly offers ±0.12% ohms accuracy @ 0°C. A Conax PG2 sealing gland seals the cable exiting the chamber. This product, one of the available configuration options of the Conax "Sterisensor," provides superior quality at a very competitive price.

The SL100 Steriprobe® (Sterimaster® in the USA), load/chamber probe was developed specifically to meet the demanding conditions presented by the chamber environment found in modern autoclaves. The sensitivity and accuracy of the sensor meets the requirements of current European and USA legislation whilst being of robust mechanical design.
The 'Steriprobe' has been designed to withstand these conditions and offers a reliability factor surpassing that previously obtainable. During manufacture every weld undergoes NDT examination and each completed assembly is 100% tested.
These units are available as PT100 resistance thermometers to all tolerance classes and with 3 or 4 wire connection also as type 'T' thermocouples in Class 1 material. They can be supplied in single, duplex or triplex detector format with probe lengths to requirements.
The assembly materials of construction are 316L stainless steel, PTFE and silicone and all components have full traceability.

Our customer, an aerospace composite parts manufacturer, wanted to replace their heater power feedthrough in an aerospace parts autoclave.
While it was intended to be an exact physical replacement of an existing product, Conax developed a "plug and play" solution offering several key advantages. The most important feature was its ability to be rebuilt in the field.
This product is a custom-designed hybrid of our Electrode Gland (EG) series and out Electrode Gland Teflon (EGT) series designs. We incorporated and combined positive features of each gland to benefit the customer in this application.
The EG offers high temperature resistance required closer to the heaters. The EGT offers more robust, less costly components for the balance of the assembly located where lower temperatures prevail.
The special solid nickel conductors are designed with staggered lenghts to ease power cable attachment.
Performance and longevity were inproved with this design because the heating elements can function at peak performance at all times, reducing cycle times. The few replacement parts required can be replaced on-site in the time it takes for the unit to cool down and be reloaded with new production material. The old design required a complete offsite rebuild over several months with a significant loss of productivity.
If you have a need to manage power or instrument leads into any type of an autoclave, look to Conax Technologies for your solution.

Conventional methods of chamber entry for validation thermocouples allow only limited numbers of thermocouples to be used. They are relatively time consuming in their application and frequently prone to unacceptable leakage.
The TCEG/1 addresses both these problem areas by providing individual slots for 18 separate thermocouples and a rapid action, locking and securing mechanism.
By utilising a three part sealant arrangement the gland becomes a TCEG/2 with the opportunity of increasing the capacity to 36 individual thermocouples. Should even more thermocouples need to be accommodated, then a ‘Y’ adapter connected to the chamber entry port can double both these quantities.
For mounting onto the autoclave chamber the TCEG is supplied with a Tri-clamp flange with the option of having a 1½” or up to 2½” flange.
The gland body is machined from 316L stainless steel with the cap in CZ121 brass. Sealants are in medical grade silicone to Shore 40 hardness and in accordance with FDA USP Class VI.

Validation Thermocouple Wire and Looms (VTFP):
It is a regulatory requirement when validating autoclaves and lyophilizers that Type ‘T´ thermocouples of Class 1 material grade are used.
The VTFP validation thermocouple wire meets this requirement and is supplied either in pre-cut lengths from 1 metre upto 100 metre with a formed hot junction, the hot junction can be left bare or encapsulated in a Teflon tip. The cable can also be supplied on 100/300 metre long reels.
When considering the temperature mapping of large chambers and when multiple thermocouples are to be used, this material can be supplied as a cable loom. This approach eases the installation and general handling of multiple thermocouples and offers a more protective arrangement. All the conductors are identified with an ID number to ease location identity and connectivity.
When required the thermocouple cold junctions can be fitted with miniature or standard size thermocouple connectors.
