Z-Plus Temperature & Humidity Chamber Options

Listed below are the options that are available on CSZ Z-Plus test chambers.
Cabinet Options / Instrument Options / Performance & Refrigeration Options / Humidity Options


Cabinet Options

Additional Chamber PortsAdditional Access Ports

Additional circular, square, or rectangular ports are available in a variety of sizes. Ports may be
placed on both sides of the chamber for ease of cable routing.


Chamber Glove PortGlove Ports

Two feed through ports, typically placed in chamber door, with protective gloves designed to reach in chamber and turn off/on test devices while chamber is in operation. Available on ZP-16 and up.


Cable NotchCable Notch

If routing cables through side ports is not an option for you, a cable notch may be placed in the front of your chamber.


ZP Test Chamber ShelfShelving

Additional product shelves are available for each CSZ chamber. Custom shelves and fixtures are also available.


Stainless Steel ExteriorStainless Steel Exterior

If you prefer a chamber with stainless steel exterior, CSZ can include this as an option on any chamber you request.


Instrumentation Options

EZ-View Chamber SoftwareWindows-Based Software Package

CSZ EZ-View software is available for monitoring and controlling up to 20 chambers from any location.



Chamber Hi-Low LimitRedundant Temperature Limit & Alarm

Provides essential failsafe over/under (hi/low) temperature protection for your valuable test items.



IEEE InterfaceIEEE-488 Computer Interface

A parallel interface can be provided for interface with IEEE-488 parallel instrument control buss. A standard IEEE-488 connector is provided for easy connection to adjacent test equipment. This option cannot be used in conjunction with RS-232/RS-485.


Chart RecorderChart Recorders

A selection of one or two pen chart recorders are available with a variety of pre-printed charts or self printing thermal charts.


Run Time MeterRunning Time Meter

The optional run time meter includes a non-resettable display which will accumulate the system running time for routine maintenance and planning purposes.


Main Power DisconnectMain Power Disconnect

Provides an additional level of safety by shutting down the main power to the chamber prior to maintenance or repair.


Customer Event OptionCustomer Event Option (Digital Outputs)

Includes 15 event outputs with connection panel & removable plug connectors. Designed to turn customer’s electronic DUT’s (devices under test) ON or OFF at various stages of the customer programmed test profile. Each output may also be configured to perform other operations including alarm or profile status indicators.


Digital Input OptionDigital Input Option

Includes connection panel and 8 inputs that can be configured to perform various controller functions (i.e. start, hold, resume or terminate a profile, advance steps, control customer event outputs, etc.)


EZT Monitor Package

(provides 8 thermocouple / TC inputs through EZT-570i)
EZT Monitor OptionDesigned to consist of eight (8) “T” type thermocouples (TC’s) for temperature readout with individual alarms, displays, and data logging for each input that can be monitored by the EZT-570i and the EZ-View software. The “black-box” unit itself will be mounted to the side or rear of the unit and the eight TC’s will pass through one of the existing side ports. These are TC’s only (no RH sensors or PT100-RTD’s) and are used for product temperature monitoring or temperature uniformity check within the chamber. (For monitoring only, no control.)

Watlow F4 ControllerOptional F4 Controller

CSZ F4 Programmable Controller with Product Monitor, redundant high/low limit and EIA 232/485 Computer Interface. Replaces EZT-570i and mounts on a special fixture below the door.


Performance & Refrigeration Options

LN2 Boost OptionCO2/LN2 Boost Cooling

Boost cooling is available for applications that require a fast pulldown rate. An LN2 supply tank is required with a pressure of 25 psi.

Dry Air Purge Dry Air Purge System

A dry air purge system can be provided to reduce condensation within the chamber and on the test item during temperature cycling testing. This option is primarily used to prevent short circuits in electronic components and is also used for low humidity requirements.

Remote Refrigeration

Allows the testing chamber refrigeration system to be located approximately 50 linear feet away from the chamber. This option is commonly used for labs with space restrictions or to minimize noise levels.

Refrigeration Sound Deadening

Although CSZ chambers are quiet operating, sound foam is available as an option to further reduce the noise generated by the refrigeration system. This option is commonly used in larger horsepower chambers.


Humidity Options

Recirculator WaterRecirculating Humidity Water Supply

For customers that do not have a deionized water supply, CSZ provides a recirculating water system that collects condensate from the chamber, stores it and then filters it in a reservoir for reuse.

Low Relative Humidity

For tests requiring humidity levels below 10% RH, CSZ provides an optional low humidity system for testing down to 5% RH.

Humidity Water DemineralizerHumidity Demineralizer Water Filter System

Demineralizer removes water impurities and minerals that can harm your test chamber. Cartridges will turn orange-brown when used and are easily replaceable. Additional demineralizer cartridges are available for overnight delivery.


Water Pressure RegulatorWater Pressure Regulator

Water pressure regulator is recommended to regulate incoming water supply to <=25 psig.



Reverse Osmosis Reverse Osmosis Water System

Water purification system for use with city / tap water. This option is not needed if chamber has demineralizer filter system.
