The Quantrol series is available in the three DIN formats 48 mm x 48 mm, 48 mm x 96 mm, and 96 mm x 96 mm. It is used for two-state and three-state control applications as well as for the control of regulating valves or SCR power controllers via a continuous controller output. The universal analog input for RTD temperature probes, thermocouples, or current/voltage sig nals is user programmable. The setpoint value, the actual value, and all parameters are dis played on two seven-segment LED displays (red/green) with one or two decimal place(s). The values can be displayed in °C or °F. Depending on the format, up to five relay outputs with a switching capacity of 3 A / 230 V or up to four logic outputs 0/14 V are available. The switch po sition of the relays or logic outputs is displayed using yellow LEDs. Different functions can be as signed to these outputs. An analog output 0 to 10 V or 0(4) to 20 mA is configurable as continuous controller output, actual value output, or setpoint value output. Using the binary input, the device settings and operation can be locked, a ramp or the timer can be activated, or self optimization can be initiated. The supply voltage is optionally AC 110 to 240 V or AC/DC 20 to 30 V. The controller has a ramp function with adjustable gradient for constant setpoint change. In ad dition, a special firing curve for small pottery kilns can be used which allows controlled starting and time dependent firing. The user can enter setpoint values, gradient, and firing time directly at the device. The device can be connected to host systems or devices using the RS485 serial interface. In stead of operating the device from the front, the user can also program the controller using the setup program and USB interface; this requires no additional voltage supply for the controller. The Quantrol series, like all JUMO controllers, is also equipped with reliable JUMO self-optimi zation (autotuning)
Picking a Compressor? Here’s What to Know
Please confirm the compressor is in stock and verify its core specifications before purchasing. We prioritize matching you with inventory from your local distributor, We provide actual photos for your confirmation before packaging and shipping.

FAQs
Q1: For our application (e.g., Cold Storage vs. Process Chilling), should we choose Screw, Reciprocating, or Centrifugal compressors?
A: The choice depends on capacity and application. We recommend: Screw for large, stable loads and high efficiency; Reciprocating for smaller capacity or specialized low-temperature use; and Centrifugal for very high-capacity HVAC/chiller applications. We offer a data-driven sizing analysis.
Q2: Are your system accessories (e.g., oil filters, valves, controls) proprietary, or can we easily source compatible, standardized replacement parts globally?
A: Our systems are designed with industry-standard interfaces and utilize high-quality, globally recognized components. We ensure that critical accessories and spare parts are readily available through our own supply chain and cross-reference to minimize emergency lead times.
Q3: How do you precisely calculate the required cooling load (BTU/hr or kW) and determine the correct compressor size for my specific process/cold room?
A: We perform a comprehensive heat load analysis that considers ambient temperature, product load, air infiltration, insulation U-values, and processing time. We use this data to select a compressor with the optimal capacity and EER/COP (Energy Efficiency Ratio/Coefficient of Performance) for your target temperature.
Q4: What is the warranty period for your main compressor unit and core accessories, and what is your guaranteed lead time for emergency spare parts?
A: We provide a comprehensive warranty package (typically $12$-$24$ months on the compressor). We maintain a global inventory of critical spares and commit to an emergency parts lead time (e.g., $24$-$72$ hours to major industrial hubs) to ensure minimal operational disruption.
Q5: What is the system's Total Cost of Ownership (TCO), and what technologies do you employ to maximize energy efficiency (SEER/IPLV)?
A: We provide a detailed TCO breakdown encompassing purchase, installation, maintenance, and projected energy costs. We prioritize Variable Speed Drive (VSD) compressors and advanced control systems to modulate capacity, minimizing energy consumption during part-load operation and maximizing long-term savings.
Q6: We conduct annual targeted procurement of compressors and repair kits to sustain production. I'd like to know if there are any contract discounts available?
A: Absolutely. Our primary strength lies in supply capability. Whether it's OEM manufacturing or global inventory searches—from components to complete units—we can match your needs with the nearest partner's inventory for rapid delivery. Our global alliance enables transactions at wholesale agency rates. Welcome aboard! Cheers!!
