During this period, company was engaged
in designing and developing simple but innovative electronic instrumentation
and controls that were custom built. We were trying to replace,or trying to convert,
physical phenomenon into reliable measuring signals, controls etc. Most of
the designs were based on analog circuits and have gained a good knowledge and expertise
in analog circuit design. Most of such analog design building blocks were not so reliable those days and one had to
struggle to reduce electrical noise and design for EMI / EMC. This means we had to build our knowledge
and expertise and sharpen our skill in analog design techniques.
The company was approached by a small OEM engaged in manufacturing of
washing machine, to design and later to supply
controllers for their products. Although initial quantity
was about 30 pieces per month, we took it as a great responsibility. They increased the quantity to 250-300
pieces per month within two / three months (seeing the customer acceptability
of these products). Very soon major players in this field approached us
for designing and developing electronic washing machine controllers in order to replace their existing electro-mechanical timers.
We, together with OEMS could add quite a lot
of new features and value addition to their end products. Around the middle
of 1995 there was slump in the white goods market due to some
govt. policies, higher interest rate etc. The washing machine controllers that
we manufactured for OEMs were not moving as it was earlier. We had to find same ways
in order to cater our educated, experienced and skilled work force.
Our company was approached by two major OEMs engaged in the manufacture of
air conditioners. We have designed and developed controllers for their
newly introduced "Split airconditioners". Since we had lot of
expertise in designing and developing reliable "analog controllers", this was an easy
assignment. Market share of these OEMs increased
very much and they demanded more quantity from us. Many new techniques on manufacturing and
quality assurance were introduced during this period. Many of
our major OEMs appreciated our efforts and also extended their suggestions.
Seeing this big jump in market share
of their competitors, many other OEMs engaged in the manufacturing of airconditioning products,
approached us for designing and developing controllers.
These products had quite a lot of extra features which contributed in value addition
By this time PRESEVI got into "microcontroller" based designs from the mere analog
with a humble start. Very soon most of the products were designed
around microcontrollers. Our OEMs could deliver a truly "mechatronic"
products to their customers and could attain increased market share.
Presevi designed and developed many electronic
controllers for chillers, Package air conditioners, humidity & temperature
controllers, Precision air conditioning systems etc. We also introduced controllers
with communication ports and BMS connectivity.
During this period PRESEVI introduced documentation
of all our procedures and obtained ISO 9001:2000 certification
for design, manufacturing and service activities. The company has
grown in size, knowledge, expertise and skill. We could also introduce AMF panels for motor generator sets,
aircondition controllers for Military
communication vehicles meeting strict IEC,
EMI / EMC and IP 65 specifications. We also introduced BMS
systems and several energy monitoring and saving controllers. In many organisations major energy consumption
is by the air conditioning system and therefore PRESEVI introduced
a damper operated economiser / free cooling controller (that will let outside air
based on the enthalpy in conditioned space and ambient.
We also published documents and put them in our website www.presevi.in
about the details regarding our controllers. Our
customers could download these documents from our website and meet their requirements.
The company concentrates in designing and developing high technology controllers and have got fairly good customer base.
