UV Radiator: Equipment tab

Variable Definitions, Ranges and Default Values

The following table shows the meaning of the variables appearing in this tab, as well as their default values and their generally acceptable range. Note that due to the manner by which the variables are used by the sizing and costing equations, the range of acceptable values may be further reduced.

Variable	Default Value	Range

◙ Rated Throughput The rated throughput of the vessel.	0.0 L/h	Positive
◙ Max Throughput The maximum volume that a unit of this type is available for purchase in the market.	11340.0 L/h	Positive
○ No. of Lamps Number of Lamps used per unit.	5	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Consumable

This equipment requires use of a ‘UV Lamp’ consumable. A sample of such consumables is predefined in the database: 65.0 Watts lamp with a wavelength of 254nm. More can be added easily by the user (see UV Radiator: Consumable tab).

Sizing: Design Mode

In Design Mode of calculation, the program calculates the operating throughput (in L/min) and if it is greater than the maximum throughput that a unit can handle, it assumes multiple units operating in parallel.

Sizing: Rating Mode

In Rating Mode, the program divides the operating throughput by the equipment’s rated throughput to estimate the equipment capacity utilization.

Costing

The equipment purchase cost is based on the throughput. By default it is calculated by the program’s built-in model for a UV Radiator.
