## Abstract

Cooling medium circulation systems for supplying a cooling medium through a single header to multiplexed heat exchangers are described. In an aspect, a system includes, but is not limited to, a storage tank configured to hold a cooling medium in a fluid state; first and second circulation pumps fluidically coupled to the storage tank; a single cooling medium header fluidically coupled with each of the circulation pumps; a first dryer module configured to direct a first portion of cooling medium from the single cooling medium header past a first stream of compressed air and to direct the first portion of cooling medium back to the storage tank; and a second dryer module fluidically configured to direct a second portion of cooling medium from the single cooling medium header past a second stream of compressed air.

## Claims

### Claim 1

A system for circulating a cooling medium to condense moisture held in compressed air, the system comprising:
a storage tank configured to hold a cooling medium in a fluid state within an interior of the storage tank;
a first circulation pump fluidically coupled to the storage tank;
a second circulation pump fluidically coupled to the storage tank;
a single cooling medium header fluidically coupled with each of the first circulation pump and the second circulation pump;
a dryer module fluidically coupled with each of the single cooling medium header and the storage tank, the dryer module configured to direct a portion of cooling medium received from the single cooling medium header past a stream of compressed air to condense at least a portion of moisture held in the stream of compressed air, the dryer module configured to direct the portion of cooling medium back to the storage tank.

### Claim 2 (depends on 1)

The system of claim 1, wherein the single cooling medium header is fluidically coupled with each of the first circulation pump and the second circulation pump via separate fluid lines.

### Claim 3 (depends on 1)

The system of claim 1, wherein the storage tank includes a baffle in the interior configured to mix cooling medium received from the dryer module.

### Claim 4 (depends on 1)

The system of claim 1, wherein the dryer module includes an outlet that is fluidically coupled with the storage tank via a fluid line.

### Claim 5 (depends on 4)

The system of claim 4, wherein the storage tank includes a baffle in the interior, and wherein the fluid line includes a portion directed towards the baffle to mix cooling medium received from the dryer module.

### Claim 6 (depends on 1)

The system of claim 1, wherein the dryer module includes a chiller configured to reduce a temperature of the portion of cooling medium following condensation of at least a portion of moisture held in the stream of compressed air and prior to directing the portion of cooling medium back to the storage tank.

### Claim 7 (depends on 1)

The system of claim 1, wherein the first circulation pump is fluidically coupled to the storage tank via a first fluid line.

### Claim 8 (depends on 7)

The system of claim 7, further comprising a first valve coupled between the first circulation pump and the storage tank on the first fluid line.

### Claim 9 (depends on 8)

The system of claim 8, further comprising a second valve coupled between the first circulation pump and the single cooling medium header.

### Claim 10 (depends on 7)

The system of claim 7, wherein the second circulation pump is fluidically coupled to the storage tank via a second fluid line.

### Claim 11 (depends on 10)

The system of claim 10, comprising a first valve coupled between the second circulation pump and the storage tank on the second fluid line.

### Claim 12 (depends on 11)

The system of claim 11, further comprising a second valve coupled between the second circulation pump and the single cooling medium header.

### Claim 13

A system for circulating a cooling medium to condense moisture held in compressed air, the system comprising:
a storage tank configured to hold a cooling medium in a fluid state within an interior of the storage tank;
a first circulation pump fluidically coupled to the storage tank;
a second circulation pump fluidically coupled to the storage tank;
a cooling medium header fluidically coupled with the first circulation pump via a first fluid line and with the second circulation pump via a second fluid line;
a dryer module fluidically coupled with each of the cooling medium header and the storage tank, the dryer module configured to direct a portion of cooling medium received from the cooling medium header past a stream of compressed air to condense at least a portion of moisture held in the stream of compressed air, the dryer module configured to direct the portion of cooling medium back to the storage tank.

### Claim 14 (depends on 13)

The system of claim 13, wherein the storage tank includes a baffle in the interior configured to mix cooling medium received from the dryer module.

### Claim 15 (depends on 13)

The system of claim 13, wherein the dryer module includes a chiller configured to reduce a temperature of the portion of cooling medium following condensation of at least a portion of moisture held in the stream of compressed air and prior to directing the portion of cooling medium back to the storage tank.

### Claim 16 (depends on 13)

The system of claim 13, wherein the first circulation pump is fluidically coupled to the storage tank via a third fluid line.

### Claim 17 (depends on 16)

The system of claim 16, further comprising a first valve coupled between the first circulation pump and the storage tank on the third fluid line.

### Claim 18 (depends on 17)

The system of claim 17, further comprising a second valve coupled between the first circulation pump and the cooling medium header on the first fluid line.

### Claim 19 (depends on 16)
