VI. GENERAL DESCRIPTION
Torrey Pines Scientific IC25/35 units are Peltier driven for chilling & heating. They come
with a universal power supply and the chilling/heating module. The units have only one
moving part, the DC fan that cools the unit. Everything else is solid state and should last
years without problem. All functions of the unit are accessible from the front panel via the
membrane switch and accompanying digital display.
HEATER/CHILLER PLATE
The surface is a very flat aluminum plate designed for good contact with any flat surfaced
item placed on it. The plate size of the IC25 is 2.875" (73 mm) x 4.375" (111 mm). It will
chill and heat quickly without a load on it. The temperature of the plate is sensed by a
platinum RTD mounted under the plate. The temperature controller in the unit compares
the plate temperature with the target temperature and instructs the Peltier module to heat
or chill the plate as required to keep them equal.
PROGRAMMABLE
All IC25/35 units enable the user to define up to 5 individual programs consisting of up to
10 steps per sequence. All sequence steps are stored in non-volatile memory.
TIMER
All units have a countdown timer reading in hours, minutes, and seconds. It can be set to a
maximum of 99 hours 59min 59sec. The timer will be displayed at the same time as the
SET POINT and PLATE TEMP. It has a user settable AUTO-OFF as well. This works to
turn the chiller/heater target temperature off when the timer counts to zero.
ALARM
The units have an audible alarm that sounds for one minute when the timer counts down to
zero. Touching the UP ARROW will turn the alarm off during this first minute. However, if
the alarm sounds for the entire minute, it will shut-off the sound automatically. When the
alarm first sounds, the timer will start to count up. This lets the user know how much time
has passed since the timer first sounded.
