The Heat Treatment industry in India is growing by leaps and bounds. However, increasing customer awareness, the rising costs of carburizing fluids and energy are causing Heat Teeters to be increasing conscious about

Incorrect Carbon absorption
Incorrect case depth
Insufficient case carbon
Too much carburization resulting in fractures
Too much energy consumption
Too much fluid consumption
Too many reworking

The Fykays Automatic Programmable C-Pot controller is the perfect solution to all the above problems. .

FYKAYS MICROPROCESSOR BASED C-POT CONTROLLER:

The C-POT CONTROLLER works on the well–proven Zirconia sensor principle which enables detection of Oxygen in the furnace from PPM level to PPB levels. The C-POT CONTROLLER has been specifically developed to monitor the precise Carbon Potential in the furnace atmosphere whether it is Pit type, SQ or a Continuous furnace. Whether a manual system is opted for, or a fully automatic unit with multiple cycles, Fykays’ C-POT CONTROLLER enables heat treaters to achieve high standards of Carburizing, Carbonitriding etc operations.
Some salient features of the system are:

Multiple segments are within the capability of the C-POT CONTROLLER, in terms of carburizing, Diffusion, Soaking etc.
The multi segment programmable controller provides for Nitrogen sealing of the job during soaking.
The C-POT CONTROLLER helps to regularly achieve high product homogeneity, reduction of enrichment fluid and reduced energy consumption and most importantly avoid any re-working.
It is designed to accept dual inputs- from the thermocouple and Oxygen sensor.
Four 1” displays showing RTC, C-POT value and temperature and operational status near the furnace enable the operator to precisely control his schedules.
Extremely easy to install and operate
Can be installed within a matter of hours
Virtually maintenance free PROGRAMMABLE C-POT CONTROLLER FROM FYKAYS ENGINEERING (P)LTD. 2014
It comes with a lot of built in features like RTC, Hi- Lo Oxygen set points indication facility, Trial output for fluid feed control, time proportionate ON/OFF control, system alarm for thermocouple failure, Probe temperature over range and very high probe cell voltage, etc.
Data logging, alarm indications, computer compatibility etc.

The basic components of Fykays’ C-POT CONTROLLER are as follows:

Oxygen Probe: The Zirconia Oxygen probe which senses the Carbon potential in the furnace.
C-POT CONTROLLER suitably panel mounted.
The reference air system
The electronic purging apparatus
The remote display: with Hi/Lo alarm
Trim by-pass manifold.
Accessories like special umbilical cord etc.

Fykays C-POT CONTROLLER promises to reduce fluid consumption by as much as 20% and reduce energy consumption by about 10% and zero re-working. Under these circumstances, this system is a MUST for all carburizing furnaces particularly when the payback period for this system can be as low as a few weeks to a maximum of couple of months.

FYKAYS offer two distinct types of IN-SITU PROBES

Reaction Bonded: (RB) unsheathed probes
Fusion bonded: (FB) sheathed probes

Reaction bonded probes, which can be used without external sheathing and the associated assembly and maintenance problems make use of a patented process in which a ZrO2 thimble or pellet is bounded onto an Al2O3 tube by reaction through a platinum washer.Fusion bonded sensors on the other hand use sintered ZrO2 pellet cemented and fused to the Alumina tube

Wider applications :

Length of Probes

Standard lengths available are 150, 300, 600, 900, 100, 1200 and 1500 mm. Longer lengths up to 2500 mm available on special request. 

Thermocouple Specifications:

For RB sensors the thermocouples are normally type 'R' or 'S' (Pt.Pt.Rh 13 % or Pt.Pt.Rh 10 %)For FB sensors the choice is extended to 'K' type (chromel-alumel), for lower temperature applications. 

For extra temperatures probes are supplied with 'B' type (PtRh 6% - Pt 30 %) thermocouples (RB sensors only) thermocouples (RB sensors only)

Specifications :

It is the Micouple Bow to the Industry's demand/Desire for Quality, Economy and Safety. Mi Couple is supple, Durable and Accurate to the Core. It is designed to be a part of the heating structure. In that process it stands BEATINGS in the beds and TWISTINDS in the walls so that it can keep in touch with the superhot materials and transmit the process temperatures Days in and Years out. Mi Couple represents a wide range of permanent thermocouples to be useful to many industries. Mi Couple is produced by : Fykays Engineering Pvt. Ltd. Leaders in Advanced Pyrometry.

On the lop, at the bottom and the walla throughout the arduous path to the control apparatus. Nil Couple and Micab combination of Thermocouple technology is assiduously developed for superfast and accurate temperature measurement from vital spots considered inaccessible so far, as the high temperatures and hitherto undiscovered materials of construction precluded precise probe. It now facilitates rigid quality control denied thus far to the quality conscious decision makers. While helping to improve quality Mi Couple enables closer control on fuel costs. Its contribution to Industrial Safety is a very important consideration in its favour. 

Mi Couple is embedded at the critical process paint to catch the process temperature and transmit the signal to the control apparatus through Mi Cab. ft thus simplifies and hastens decision making for Quality, Economy and Safety. Whereas Mi Couple describes the Mineral insulated thermocouples, Mi Cab describes the Mineral insulated cables that truthfully complement the relay function of Mi Couple through a little less hostile environment. 

Mi Cab is the most reliable complement to Mi Couple because it shares its superfast signal transmission efficiency and resistance to the varying temperature zones of the traversing regions and also to static interferences through its exposed path. Mi Couple is made available in many versions, to serve varied industries. Whereas, the Nuclear, Aircraft, special steels, Ferro-Alloys and their like attract the Costlier versions; less exacting conditions in Dairies, Power stations, Pharmaceuticals may opt for the economic variety suited to their respective plants & processes. 

Depending on the specifications of each Industrial Process or Product Fykays offer a wide choice for Mi Couple - Mi Cab ingredients.
