New cooling circulation thermostats

The LAUDA PRO has been inspir­ing users with spe­cif­ic tem­per­a­ture con­trol require­ments since 2016. Lau­da has now extend­ed its PRO port­fo­lio to include two new low tem­per­a­ture cir­cu­la­tion ther­mostats designed for the spe­cif­ic require­ments of test bench­es, reac­tors, cli­mat­ic cham­bers and dis­til­la­tion plants in the chem­i­cal, phar­ma­ceu­ti­cal, biotech, min­er­al oil, auto­mo­tive and elec­tri­cal engi­neer­ing industry.
With a tem­per­a­ture range of ‑90 to 200 °C and a cool­ing capac­i­ty of 0.8 kW, the RP 290 E and  RP 290 EC low tem­per­a­ture cir­cu­la­tion ther­mostats are ide­al as a sub­sti­tute for dry ice in exter­nal low-tem­per­a­ture appli­ca­tions, for mon­i­tor­ing organometal­lic reac­tions, for deter­min­ing pour and cloud points dur­ing min­er­al oil analy­ses and as a cool­ing source for Brook­field tests, to name but a few exam­ples. The new RP 250 E and RP 250 EC mod­els offer a cool­ing capac­i­ty of 1.5 kW, almost twice the capac­i­ty of the RP 245 (0.8 kW), which was pre­vi­ous­ly the most pow­er­ful Lau­da PRO low tem­per­a­ture cir­cu­la­tion ther­mo­stat – with the same space require­ments. They are the first choice for sta­t­ic tem­per­a­ture con­trol tasks that require a high cool­ing capac­i­ty and involve extreme­ly rapid tem­per­a­ture changes with­in a range of ‑50 to 200 °C. Typ­i­cal appli­ca­tion areas include reac­tion mon­i­tor­ing in the chem­i­cal and phar­ma­ceu­ti­cal indus­tries as well as long-term tem­per­a­ture tests, func­tion and stress tests, cli­mate sim­u­la­tions and bat­tery tests in the elec­tric mobil­i­ty sec­tor. All new devices have a heat­ing out­put of 2.5 kW. A min­i­mum fill­ing vol­ume of 2.4 liters and an addi­tion­al expan­sion vol­ume of two liters serve as a buffer to coun­ter­act ther­mal­ly induced vol­ume expan­sion, even on larg­er con­sumers. The stan­dard use of nat­ur­al refrig­er­ants and a pow­er­ful, adjustable pres­sure-suc­tion-pump round off the range of tech­ni­cal equip­ment togeth­er with a hybrid cool­ing sys­tem that cools the air of the refrig­er­at­ing machine and simul­ta­ne­ous­ly allows water cool­ing to reduce the dis­si­pa­tion of heat into the environment.
All Lau­da PRO devices are fit­ted with a detach­able, intu­itive­ly oper­at­ed con­trol unit: The Base mod­el pro­vides a bright, high-con­trast dis­play OLED dis­play with soft­keys, while the Com­mand Touch oper­at­ing unit (all mod­el vari­ants with addi­tion­al let­ter ‘C’) offers indi­vid­ual pro­gram­ming, pass­word-pro­tect­ed user man­age­ment and a USB inter­face for data exports. The bright 5.7 inch touch screen can even rec­og­nize the touch, swipe and zoom ges­tures of users wear­ing gloves – a valu­able ben­e­fit in the laboratory.
