PRODUCT DESCRIPTION

Technical specifications

Inner dimensions (w x d x h):           500 x 550 x 550 mm

Work space (w x d x h):                    380 x 400 x 450 mm

Outer dimensions (W x D x H):        1,250 x 1,040 x 2,260 mm

Transport height:                             1,980 mm

without exhaust hood

Weight:                                            760 kg

Load weight (max.):                         130 kg

uniformly distributed load

Distributed load (max.):                  5 kg/dm²

Tmax:                                              1,800 °C

Temperature uniformity:                ± 6 K at 1,450 °C

Value according to DIN 17052-1 in the empty work space

Calibration to temperature point by the customer or optional TUS measurement

Max. working temperature:            1,750 °C

Long holding times close to the maximum temperature lead to higher wear of the furnace.

Thermocouple type:                       type B

Connection (electr.):                       220 V, 3/PE, 50 Hz

fuse protection without earth-leakage breaker

Power rating:                                  21.5 kW

Door Type
 Chain-guided parallel moving swivel door for precise operation, protecting the collar fibre insulation
 Door area armoured with stainless steel
 Safe and tight closing of the door with labyrinth sealing

Heating
 Heated from both sides by molybdenum-disilicide heating elements
 Vertically mounted heating elements provide for free heat radiation in the furnace chamber, which results in a very good temperature uniformity in the upper temperature range
 In case of possible process-related interactions between batch and heating elements, also heating elements in other qualities can be offered as retrofitting set. We would be pleased to assist you accordingly.

Stainless Steel Exhaust Hood

 For connection on customers duct work
 Ø 150mm outlet in the middle of the hood
 Position adjustable in height

Controller P570
 The controller series 500 impresses with its unique scope of performance and intuitive operation. In combination with the free “MyNabertherm” smartphone app, the operation and monitoring of the furnace is even easier and more powerful.
 Operation and convenient programming via a large, colorful, a high-contrast 5 inch touch display
 50 programs with 40 segments each can be saved
 Precise temperature control
 Max. 6 segment-wise, switchable functions for controlling additional electrical equipment
 Increased process reliability due to different operator levels
 24 languages selectable
 Information menu with status messages
 Adjustable alarm functions, e.g. for temperature behavior
 WLAN module for connection to the MyNabertherm app
 USB interface for import and export of data

MyNabertherm App
 Convenient monitoring and overview of one or more Nabertherm furnaces simultaneously
 Graphic and tabular display of process progress and alarm messages
 24 languages selectable
 Error messages via push notification
 Contact with Nabertherm service possible via mobile device; furnace data are stored in the app

Freeware NTEdit for program editing on a PC
 Clearly structured editing of programs on a PC
 Export and import of programs via customer’s USB stick
 Graphical overview of the set temperature profile on a PC
 MS Excel required

NTLog/NTGraph for Nabertherm controllers
 Process documentation by means of data recording on customer’s USB flash drive
 Storage in CSV format, evaluation via spreadsheet program (e. g. MS Excel)
 Recorded data: time difference, segment number, temperature set points, actual temperatures, power outputs, control functions
 Software tool NTGraph (freeware) to visualize the process data in MS Excel
 8 prepared sets for curve design (color, scaling or naming), individually adaptable
 This charge-free tool is excluded from warranty; there is no entitlement to support. In case NTGraph is not compatible to your PC system another spreadsheet program can be used for data evaluation.

Switchgear
 Mounted in the side of the furnace housing
 Softstart switch
 With this function, the heating output will be limited to an adjustable temperature in the lower temperature range. Independent from the set temperature the furnace heats only with the limited soft start function. The adjustment will be set in the controller
 As protection for the product in the lower temperature ranges
 Switching of the heating elements by thyristors in phase-angle mode
 High-grade power transformer
 Ammeters to monitor the electrical load
 Main switch

Temperature limit controller
 Over-temperature limiter with adjustable cut-out temperature for thermal protection to protect furnace and load
 Temperature measurement via independent thermocouple
 Temperature display in °C, alternative configuration in °F possible, must be specified with order
